UHHHMMMM.......... When I tested it in GameMaker Studio 1.4, it gave 2 errors in the script GenerateCurrentFrame
line 84 pos 185 Unknown function or script: sound_add
line 113 pos 190 Unknown function or script : sound_add
which YOYO depreciated. I commented out those lines and got another error
"############################################################################################
FATAL ERROR in

stack frame is

"
which I don't comprehend, at least at the present moment.
So that's where I am for now. This weekend I'll peruse on the code and try to solve it. You'll probable hear from me either Tuesday or later depending on how I get through on some other work I'm doing this weekend. Doing freelance work dosen't let one have a strict schedule. One must be flexible.
So have fun

and enjoy your weekend
