Webmaster Forum / Flash / Flash Actionscript / July 2007

Why I can use movie clip as a button in some fla, but not in others. Here is
error message I got: "**Error** Scene=Scene 1, layer=ActionScript, frame=1:Line
8: Left side of assignment operator must be variable or property.
     mc-lashbtn.onRelease = function () {..."

Please help.

Thanks in advance.
