First post - AS3 Arrow Keys not looping my walk cycle

Hello People,
This is my first post here. I am currently trying to make a flash based game. In my codes below line of code:
if(RightKeyisDown)
{
Jason.x+=speed;
Jason.scaleX =0.63;
Jason.gotoAndStop(2);

The (2) frame in movieclip JASON contains a walking animation, however, I believe my arrow keys are simply reapeating the events when I hold it down, so my animation never plays.

How do I get my loop to actually play? I tried putting the* gotoAndStop* in my *PressAKey *definition function, but the animation only plays once.

Thanks in advance. Sorry if this comes off as a NEWB question :stuck_out_tongue:
