The reason your screen shots are appearing in the wrong directory is because your variable "save_location" is fine, but then you add "the quoted form of Poxix path of save_location" -- you're gilding the lily and the computer doesn't know what's up.
if "ss" is a folder, save_location should end with a "/". So ...
Code:
set save_location to ¬
"'Users/Fahad/Desktop/ss/'" -- assuming ss is a folder
repeat with shotcount from 1 to 2
do shell script "screencapture " & save_location ¬
& "screen" & (shotcount as string) & ".jpg"
delay (10) -- delay 3 second
tell application "System Events"
click at {1360, 450}
end tell
delay 3
end repeat
Why click isn't working, you got me. System Events is always a last resort and my guess is a) you're trying to grab pages from the amazon.com web site, and b) their programmers figured somebody might do this and are handling mouseclicks just differently enough to prevent someone from pulling this off.
I realize it's way too analog for the 21st century, but you might try a library.
