macOS Applescript / Automator Renaming a File

[itsmrjon]

Let me begin by thanking you for taking a look at this =)

I'm attempting to write an app for myself that renames/organizes my TV show library (EyeTV is rather bad at this after exporting), however I have run into a minor glitch that for the life of me I haven't been able to figure out.

This applescript is part of a larger automator workflow. However this section is intended to rename the TV Show as such:
Name of Show - S01E01.extension
From:
Name of Show - Episode Name.extension

This applescript is contained within automators "Run Applescript"

on run {input, parameters}
	
	tell application "Finder"
		set theFile to input
		set filePath to theFile as text
		set TID to AppleScript's text item delimiters
		set AppleScript's text item delimiters to ":"
		set fileName to last text item of filePath
		set AppleScript's text item delimiters to "."
		set baseName to text item 1 of fileName
		set extName to text item 2 of fileName
		
		set AppleScript's text item delimiters to {"s01", "s02", "s03", "s04", "s05", "s06", "s07", "s08", "s09", "s10", "s11", "s12", "s13", "s14", "s15", "s16", "s17", "s18", "s19", "s20", "s21", "s22"}
		
		set showName to text item 1 of baseName
		
		set AppleScript's text item delimiters to {"e01", "e02", "e03", "e04", "e05", "e06", "e07", "e08", "e09", "e10", "e11", "e12", "e13", "e14", "e15", "e16", "e17", "e18", "e19", "e20", "e21", "e22", "e23", "e24", "e25", "e26", "e27", "e28", "e29", "e30"}
		
		set episodeName to last text item of baseName
		
		set AppleScript's text item delimiters to episodeName
		set trimmedName to first text item of baseName
		
		set AppleScript's text item delimiters to showName
		set seasonEpisode to last text item of trimmedName
		
		set finalName to showName & "- " & seasonEpisode & "." & extName
		set AppleScript's text item delimiters to TID
		set name of theFile to finalName [COLOR="Red"]<-- this is the line giving me problems[/COLOR]
		
	end tell
	
	return finalName
end run

Now as it is written, finalName is returned as I wish it to be (in the format mentioned above). However the line intended to rename the file is giving me an error

Can't set name of {alias "SSD:....."} to "Alphas - S01E01.m4v". (-10006)

Could someone please tell me what I am doing incorrectly with the rename?
If you could suggest a correction that would work I would appreciate it.

Also, feel free to use this for personal use, I know it's not the best code (quite frankly I think it's horrendous because this is the second applescript I've ever written), but if you find it useful just please cite me =)

Thanks again!

The input parameter is a list (even if there is only one item), so normally you would repeat through the items in that list. If your workflow really only handles one input item, then just coerce the item in the list (like you did when setting the filePath), e.g.

set theFile to the first item of the input
