Before I ask what I hope it my final question, I want to say thanks for all
the help. This is my first infopath project and it is a little ambitious for
a first attempt. I've gotten everything working with one exception. Here is
the problem, i was hoping someone could help me. I'm pretty sure I should be
using the current function somehow but i don't really know how.

I have a repeating table that has a nested repeating table inside of it. I
want to set the default value of a textbox inside this nested repeating table
to a value obtained via a function that operates on a secondary datasource. I
want to count all the rows in this seconday datasource only if a field in the
seconday datasource = a field in this nested repeating table. For some
reason, it doesn't seem to work using the point-click method of building a
default value; it just repeats the same value on every textbox.

Should I be using the current function somehow? I've read some other posts
on using the current function and i don't understand how to use it if i want
to count instances in a seconday datastore, filtered via a comparrison
between a value in the repeating table and the value in that secondary data
store.

Thanks again.
