Global Variable declaration

[Yarden Sheffer]

For some reason this wont compile, it says that i need to declare the
variable before using it


on prepareMovie



global sm204

sm204 = 0

global smx204

smx204 = 0

global sm404

sm404 = 0

global smx403

smx403 = 0

end

__________________________________________________

on mouseUp

if (sm204 = 0) and (smx204 = 0) and (sm404 = 0) and (smx403 = 0) then

repeat with counter = 5 to 50

sprite(7).locV = counter + 212

sprite(8).locV = counter + 234

sprite(9).locV = counter + 256

updateStage

end repeat

sm204 = 1

end if

end

Why would you do both?

You wouldn't. Remove the word "and" and reparse.

Ehm, I meant it more like "also; it should be at the top of all those
scripts, not within a handler"
Yes, the "and" was pretty obsolete...

ok. I understand. To date I've declared my globals in each handler, but if
you can just wack the declaration at the top of the script then that might
be cleaner.

Also, less chance of a mistake if you only declare it once.

yep. Sounds as though they would be better local to the handler.
