hi, i am building a flash website with xml data.

3 problems i canīt resolve:

1. flash displays 'undefined' on empty xml fields;
2. i need to dinamically make a loadmovienum. the name of the file must be equal to the content of an xml field, and add '.swf'
3. is there a software that interprets the xml file and proposes a form more user frendly than copy paste ad infinitum?

anyone can help me? i've been all night posting threads in lots of actionscript learning sites.
