Swap function not working!

Hi everyone,

Hope you can help. I am not a master in flash, so I try to take a contemplation of tutorial and try to mix them together. however, I have come into a jam in my latest project.

I am trying to make a basic flash website. With a simple navigation menu. One of the Menu option will lead to a section that will have a Z depth action script in it. So that I can stack some pictures and the user can shuffle and move them around. However, I cannot get the swap function to work in the movie! I can get it to work on a separate and fresh .fla file, but when i do the same step in the tutorial is fails. :frowning:

I am attaching the .fla here and hopefully, someone can shed some light for me! The link that has the swap function is the "whats new"section.

Thanks in advance!

EDIT: sorry can’t upload the FLA here so i have uploaded it elsewhere. here is the link
