none of the tutorials ive been doing have been able to run the actionscript properly yet and ive been pulling my hair a bit to find out why.

im using cs4 and neither as3 or as2 seem to accept the names i give the movieclips. ive even downloaded the source files for some of the tutorials and they haven't worked either.

im uninstalling and reinstalling as im writing this, but in case the problem persists i would absolutely love to know what could be causing this.
probably going to be another program isn't it?

Thanks in advance
