    Hey All,



    I'm building a script for Final Cut Pro (7) this is a small part of the entire script and I am having some difficulties getting this to work. So, the objective is to get a number from the user, then to have the number escalate as it repeats. I also need to make this number "Paste" in. However I cannot use the cliboard functions at all because they will be in use in a different part of the script.



    What this part was designed to do, (but doesn't do all the time ) is take the number submitted by the user, and break it down by digit and spit it back out in the form of a variable key code. Another part of the script would do the escalation of the number. But what I really need is to find out why the greater than or equal to/ less than or equal to aren't correctly segmentig the numbers, so the script doesn't try to do the input number more than once.





    Code:
    set start_value to text returned of (display dialog "Start number?: " default answer "") as number
    
     
    
    if start_value is greater than or equal to 0 then
    
        if start_value is less than or equal to 9 then
    
            set start_value to start_value as string
    
            set start_value01 to 0
    
            set start_value02 to 0
    
            set start_value03 to the first item of start_value as number
    
           
    
        end if
    
    end if
    
    if start_value is greater than or equal to 10 then
    
        if start_value is less than or equal to 99 then
    
           
    
            set start_value to start_value as string
    
            set start_value01 to 0
    
            set start_value02 to the first item of start_value as number
    
            set start_value03 to the second item of start_value as number
    
           
    
        end if
    
    end if
    
     
    
    if start_value is greater than or equal to 100 then
    
        if start_value is less than or equal to 999 then
    
           
    
            set start_value to start_value as string
    
            set start_value01 to the first item of start_value as number
    
            set start_value02 to the second item of start_value as number
    
            set start_value03 to the third item of start_value as number
    
           
    
        end if
    
    end if
    
     
    
    if start_value01 is 1 then set O1 to 18
    
    if start_value01 is 2 then set O1 to 19
    
    if start_value01 is 3 then set O1 to 20
    
    if start_value01 is 4 then set O1 to 21
    
    if start_value01 is 5 then set O1 to 23
    
    if start_value01 is 6 then set O1 to 22
    
    if start_value01 is 7 then set O1 to 26
    
    if start_value01 is 8 then set O1 to 28
    
    if start_value01 is 9 then set O1 to 25
    
    if start_value01 is 0 then set O1 to 29
    
     
    
    if start_value02 is 1 then set O2 to 18
    
    if start_value02 is 2 then set O2 to 19

    if start_value03 is 1 then set O3 to 18
    
    if start_value03 is 2 then set O3 to 19
    
    if start_value03 is 3 then set O3 to 20
    
    if start_value03 is 4 then set O3 to 21
    
    if start_value03 is 5 then set O3 to 23

    if start_value03 is 8 then set O3 to 28
    
    if start_value03 is 9 then set O3 to 25
    
    if start_value03 is 0 then set O3 to 29
    
     
    
    tell application "TextEdit"
    
        activate
    
        tell application "System Events"
    
            tell process "TextEdit"
    
                key code O1
    
                delay 0.1
    
                key code O2
    
                delay 0.1
    
                key code O3
    
            end tell
    
        end tell
    
    end tell




    Text Edit being my test dummy for this part of the operation. I am on 10.8, a couple others will be on 10.7.



    Thanks for any help on this!

    The problem is that if you have a line such as:
    if start_value is greater than or equal to 100 then​
    where start_value is a string, then AppleScript will perform a text comparison - ie is start_value after, alphabetically, "100". This is true for values such as "5" or "43".

    To solve this, just convert start_value to a number first, eg:
    if (start_value as number) is greater than or equal to 100 then​
    Alternatively, change your code so that it doesn't convert start_value to a string, or use 'else if' statements rather than 'if' so that it doesn't check for multiple cases where only one should be possible anyway.

    However, your code can be greatly simplified, which avoids the problem altogether. The following is functionally equivalent to your original code (with a little extra code for error checking):

    Code:
    set start_value to text returned of (display dialog "Start number?: " default answer "")
    
    try
    	set start_value to start_value as integer
    	if (start_value < 0 or start_value > 999) then
    		-- not in the required range - do something
    	else
    		set start_value03 to start_value mod 10
    		set start_value02 to start_value mod 100 div 10
    		set start_value01 to start_value mod 1000 div 100
    		
    		tell application "TextEdit"
    			activate
    			tell application "System Events"
    				
    				tell process "TextEdit"
    					keystroke (start_value01 as string)
    					delay 0.1
    					keystroke (start_value02 as string)
    					delay 0.1
    					keystroke (start_value03 as string)
    				end tell
    			end tell
    		end tell
    		
    		-- do whatever else you want to do
    	end if
    on error e
    	-- not a number (or some other error) - do something
    end try
