Ok, I've got your new files, which both open...so I'm probably more confused as to why it didn't work before (!).

Anyway, the problem is simple. The code that is sending needs to be in the same movieclip as the fields. At the moment your button is on the stage, but all the textfields are in a seperate movieclip. Try putting the send button inside the movieclip with all the form elements and see how that does.
