I need a script to select a random order of six mcs named mc1 to mc6 (fade each down one at a time one after another) once all six have each faded up from 0 alpha to 100 I want it to randomly fade those six mcs down from 100 alpha to '0' alpha again, all one mc at a time so this loops around and goes through again.

So it selects a randoom order and fades one mc in at a time and once all six faded in all six fade out one at a time.

How can this be done I can get the fade down up thing going but how to do the random thing??
