Error in script (+hide)

[Gururaj]

I made an AHK Script about 5 years ago, and it worked well, thanks to several members of this forum.
Basically the script is used to select and search one of my Japanese-English glossaries when I select a specific phrase using a text editor called TextPad, which searches the phrase and comes up with the results.
It used to work fine but now doesn't. I have forgotten the basics of script writing and need to use this script again for my work. Will somebody kindly assist? The script is pasted below (not a large one). When I tried to edit the script I got the error shown below the script. Now, when I select a phrase in MS Word and hit windows key +Z or Windows key +X, nothing happens. The only changes I made to the script after five years is to give the paths to the various glossary files to search and the path to the TextPad program.
Thanks in advance for any assistance.

Thank you, I removed the offending + mark.
Now TextPad the editor program opens, but no luck. The phrase is not pasted in the search window nor does the GUI for selecting the glossary appears!
I seemed to remember that there was a debug feature that you could use to test the script?

You can add these two hotkeys ( of any hotkey combination you prefer that do not interfere with textpad )to have a list of last executed lines and content of variables:

!v::listvars
!l::listlines

My guess is that your program stops at WinWait, C:\Program Files\TextPad 8\textpad.exe

I think it should be:
WinWait, ahk_exe C:\Program Files\TextPad 8\textpad.exe

Use ahk_exe to identify a window belonging to any process with the given name or path.
