Hello all…  
I am hoping someone can help me. I have a flash gallery that using an xml file to pull data from. Some of my Pics have descriptions and some do not. The ones that do have descriptions work fine. The ones without come up as undefined. I am new to flash and xml. I will post my code in hopes that someone can assist me.

Thanks  
Caree
