Urgent, please help Moving x position in this code

Hi people!

I have this script, that zooms and fades the movieclip but i also need to shift the position slightly from the start state to the end state.

For example var startX = 60 var endX = 70 so when the zoom start it starts at x = 60 and slowly moves as it zooms out to x = 70.

Can anybody help please?
