Movie clips

i am pretty sure this is possible.

i have a page with some buttons that link to other MCs, whn you click the button, i have an empty frame at the top right corner, in that i have the new mc load there. the problem i face is, it loads over top of whats already in the frame.

is there a way you can clear the fram using actionscript?

what i previously have done is went to a blank frame, and in that blank frame had an empty mc and just said load new mc, but i cant keep doing this because its an area that gets updated weekly and will always be growing, and i dont want the filesize to always be growing as well.

sorry if that made no sense. if you need anything to understand better just let me know,

thank you so much.
