Pausing a movieclip

Hi

I tried to get this right but it just won’t work for me. It’s probably something very simple.
I have a video in a movieclip on my timeline. On the first frame, I have the stop(); command. I want to be able to hit the SPACEBAR: which results in pausing the movieclip and jumping to frame 2 on the timeline.

Can anybody help me with this please.

Thanks
