Re: Flash help please!
Well, I'm not all that great with AS and have never used classes (my lessons have only covered the external *.as-type classes), but do you need the 'function name(event:Event)' thing?

No, that just got me a bunch of compiler errors.

Re: Flash help please!
Most coding-type stuff, even if it isn't Scratch-related, generally goes in AT now for some reason.
Yawn.

Re: Flash help please!
Okay, I've pinpointed the problems to lines 17 and 25. Line 17 creates the "init" function, and line 25 keeps you from entering letters into the "input" box.

Re: Flash help please!
Yes! I got it! The "init" function can't be void because it has to return values! Now it's not returning values for some reason, but I got it!

Found via google ´Error #1009: Cannot access a property or method´
I was just curious, never did anything with Flash.
Do you have some Flash stuff online to see? Link to?
What Flash tools or compilers do you use?
