Random movement of Movie clips?

Right, the situation is this:

I’m trying to make it so that when the main page loads, I have two movieclips, the name of the client’s company and their slogan.

The movie clips fade in and out, but I can’t get them to appear at different places on the stage.

For example, the page loads, then “Hughes Team Racing” fades in then out in nice fancy font on the right of the stage, how do I make it so that the next time it fades in and out its at a different place?

This is probabvly an easy question but I’m a bit lost o.O

Thanks for all your help
