Scaling Movieclip... please help

hello everyone!

I am a newbie… i hope someone can help me here…

I have a map (drawn in flash) which is in a movie clip titled “map” and instance as “map_drag”.

This instance can be dragged using the startDrag(); and stopDrag(); (simple dragging so far…)

According to my design, I want to load this movieclip onto the main stage at a percentage of 50% (as the original movieclip has a width of nearly 1200 pixels…)

I have tried setting the movieclip property

map_drag._xscale = 50;
map_drag._yscale = 50;

but i think i am getting confused about what handler to put this code on to and where to put this code, on the movieclip instance or the timeline???

please help me out here…

Thanks
