What is going on here?

1

Ok so I’ve attached the .fla and .swf files for what I thought was a simple idea for a new button but for some reason when i go to test it the mask is not masked. Take a look to see what i mean. the yellow and orange squares are supposed to be masked by the text. It works fine when i scrub the time line. Not sure what I’m doing wrong here. any help is greatly appreciated.
