I need help with validation and preceding-sibling

[alantoms]

Hello,

I have a repeating table in an Infopath form. The form has two fields
which is populated from an xml file. The first field is a drop down
to select the ID. When the ID is selected the second field is
populated with a size. I have that working fine.
I run into a problem when trying to validate the drop down to make
sure that ID has not already been selected. I'm pretty sure I need to
use preceding-sibling in my validation. I have read and tested for 2
days and can not get it working. I think I am just having trouble
with the writing the syntax.

My data source according to Infopath is:
myFields
group1
tblItemizedWork
txtItem
txtSize

I really am at a wall. Can I please get some help?
Thank you for your time.
-Alan
