I updated my form, but I changed your expression a little bit, as the Part Number shouldn't need to be included as a field in the List. I adjusted this to be ParentID instead. It works! I can finally move on.
THANK YOU FOR YOUR HELP!
I would recommend that the Webinar instructions be updated, unless there is a reason why my form didn't work because it is a little different setup. I have stated before that there is an error on the first part of the instructions as well and a couple things that could be wrote a little different to eliminate some confusion. I am going to go back over it as to update my form library to not use the part number for the name of the xml. If you guys want I could make the corrections and some wording adjustments to it and send it over to you. I spent a lot of time in the graphic design/printing field, so I pay really close attention to wording and such.
Since you have my form and the templates installed on your server, could you possibly take a look at why I can't get the Part Number link to link to its form? Right now I just have the expression as a text link, I know it needs to be in the formula box, but it won't accept it there. I think that is the formula I was trying to use, I haven't looked at it in over a week.
Thanks again!
