Hi Tom,

I think I see what your saying. What if you ignored the first and 
worked on the 2nd? Same problem I guess if you hit the first child. I 
haven't tried to determine if there are two processes as a result of 
hitting the form but I know from the logs that the module starts 
cycling through the form data again.

It is probably very sloppy but my problem was that given a username 
and their file, the file was being opened twice which made parsing a 
bit tricky. All I want is to open the file once. I am open to more 
elegant suggestions though :-)
Dp.
