Tutorial for scaling w/actionscript

Could someone help me to point to a tutorial? I’d like to have 2 mc’s that scale up or down depending on which one the pointer is over. When th epointer is over mc1 it increases and the mc2 decreases equally. I have tried searching "scaling with actionscript but I don’t find anything remotely close, at least not on the first 140 topics found (or so).
Would be grateful for help:p:
