Make a balloon bigger by different user?!

I’m a beginner of Actionscript.

Would anyone help me to solve this problem?
I have a stepping animation, which should be active/count frame by frame when one new visitor hit (mousehit a button). ie. when 10 people hit, gotoAndplay frame1, when 11-20 frame 2…etc.

It maybe a off-line version (just LAN with 3 computers), or a on-line version (with PHP…) Is this the same actionscript?

Please teach me to finish this simple project. Thank you.
