haha...ok, sorry if I was vague with my original question, though, you did

manage to get at it pretty well. How then do I go about testing if a certain

movie clip exists? or, more importantly, how do I test within a whole range

of clips (named a1, a2, a3...a10) to see which exist so that I can then run

additional actionscripting on those clips? also, for curiosity's sake, is

there an answer to my original question of how flash would treat a

comparison of one number to a nonexistant number? is there a standard way it

does this, or is the script ignored, or does the flash player just freak

out?
