Mecanim animation Looping problem (Unity 4.6)

Hello, I am making a simple scroll menu for music selection (like the one Itunes has if you have used it) I have a Png sequences which I am using for that. I have made a still state for them menu and one scroll left and other scroll right and I have set up and integer which if is 1 the right scroll sequence will play and if -1 the left will. but the problem is when I change the value of int from 0 to -1 (via button click unity 4.6 UI) the state changes from still to scroll left but it keeps on looping. I have unchecked the loop time pose as well but still nothing changed. thanks in advance
