Control external movie clip from main swf - works in FP6, not in FP7 - why?

Hi,

I’m loading an external clip into the main swf, and then endeavouring to control it from the main swf. If I publish as Flash Player 6.0 it works. If I publish as Flash Player 7.0 it doesn’t work.

Why? I’m using the correct variables syntax etc…This is driving me mad!!!

I need it to be FP 7.0. The images should scroll left to right depending on what button is pressed.

Files attached - please take a look… :h:
