Help with random numbers

Hey everyone!:crazy:

Im kinda new to flash, however I am making a game, and heres the 1st boundary in my way:random numbers

I was looking at the actionscript dictionary, looked it up on kirupa.com but i couldnt really figure it out.
Could someone plz help?:crying:

What Im trying to do is generating 2 random numbers within ranges of X (220-480) and Y (70-330). Im going to be using these for new location of an MC.

Thanks in advance!
