Drag drop 'n' swap

i know, i know, but i just got to ask :slight_smile:

im dragging movie clips on to a timeline[movieclip] im trying to find a way so that they always clip onto the parent/previous clip and if necessary swap. Can somebody please point me in the right direction or offer a little fiendly advice pls?

to summarise im building up a timeline of clips whcih can be sorted within the timeline.

Thanks very :slight_smile:
