Adobe Flash CS6 movie test issue.

I've been having trouble in Flash CS6 using AS2. I have created a character with an idle animation and a walking animation. If I try to test either of them (Ctrl-Enter) it just shows the first frame. It was working when i had only one set of animations, but after adding a second it seems to have stopped working. The main reason I find this odd is because I have not added any code into the actions yet, so the reason can't be faulty code.
