Actionscript problem stacking order

Hi there!

I’m quite new in flash, but i would like to have my flash portfolio website up soon… so I decided to build a site with ‘cards’ which can be dragged around. The cards should be stacked just at random order on the site as a user enters. By clicking a card it moves to the front for viewing.
Based on the tutorial at Kirupa on 'changing stacking order (swapdepth) http://www.kirupa.com/developer/actionscript/swapdepth.htm i started flashing and scripting. I am quite pleased with the results so far, but I have one problem: When clicking a card, it really ‘swaps’ the order with the card that was up front last. Though when clicking a card, the order (and position) of the other cards should actually not change.

The .fla file can be downloaded here: http://www.basjanson.nl/portfolio.fla

Can anybody help me fixing this?

Thanks a lot in advance!!
