Can you re-post the script in a code box? @_@
Hey, (although I hate 'trial version' stuff), this is kind of a cool concept for a script... I'm going to try to write my own.
*Ahem* Well, it seems that alot of the errors are that the author uses is he puts two commas like '' and '', then uses them like quotes which are " and ". Can you tell the difference? Probably not to the naked eye, but you can in the script editor.
If you change the two commas into quotes, then the text will become violet in the script editor instead of being black or whatever. I've tested and fixed a couple more bugs in the script, but overall I'm not going to fix it all unless you re-post it in a code box, because indentation helps alot.
I also see he uses alot of weird calls like
draw_text(4, 40+4, 600, 40, "Whatever")
For one, I don't know why it's 40 + 4 instead of just 44? (meanwhile, where the part where it is y + 4 would actually make a little more logical sense, because he's adding 4 to a current 'y' value, but I'm not sure how this is used in this script yet.)
This has inspired me to write my own Scene_Activation script from scratch, which I just started on now. However, if you re-post this one I'll try and fix it for learning sake (because I probably won't finish mine.) I can try and debug it for you if its indented, because I'm sure there's alot more errors.
