Strange 1010 error

Hello all, I have been doing some research and cannot find the solution to the error I’m receiving (the ususal #1010 error). My code is really simple, every value is defined and working correctly, it seems that it doesn’t like me having multiple instances of the code below:

MovieClip(parent).nike_mc.gotoAndPlay(2);

If i have more than one of the line above, no matter what gets entered in as the instance name I still get the same error!

Any ideas?

Many thanks in advance!
