XML Next & Prev Buttons AS3

[simply]

Hey world…

One of you is my last hope. For about 3 weeks I have been stairing at this code and i cant come up with a solution. I have tried every posible thing I could think of.

What I want is “simple”, That if I click the “nxt” button, it loads the next picture in the xml. And the “prv” button goes backwards.

can someone help me. PLEEEEASE!!!
