Element is unexpected according to content model of parent

[Dan The Man]

Hi All,

I'm out of ideas on this one.. Here's the situation. I have this infopath
2003 SP1 Form with C# Managed Code. It contains a repeating table inside a
repeating section inside an optional section. Now, I need to duplicate the
Repeating Section inside the Optional Section. I have gotten it to work in
my application.. But something changed. I don't know what and not it is not
working. When I open a new Solution and recreate the same data Source and
code, everything works just fine. Below is the error I am getting. Do you
have any more ideas on what I should do to try and fix this problem?

Thanks in advance,

Dan
