How to figure out if something is sliding?

Hi in my game I want the character to NOT rotate when he is moving. I have partialy got there but when he has reached he destination he will not start to rotate again. I know how to make him start rotating again if I can figure out how to check if he is sliding. I will post pictures below and the link to the game as well. Also he faces the wrong way when sliding. http://www.stencyl.com/game/play/11488

Maybe the problem is the "Stop" block isn't letting you do anything else in the behavior? Technically you don't need that at all - or that whole Otherwise If check. If the top part isn't true, nothing else happens anyway. Unless you're intending to do something else in the future with it, you can probably remove it.

Ok I have sorted out one problem but for some reason where ever I click the box will always change to the same frame.

Then the problem is probably with your math. Try printing the value and see if it's coming out to what you expect it should.
