That Xpath code did work! Thank you! Is there a guide as to how you put that code together?

I applied similar code to the Additional Classes dropdown and it worked perfectly.

I applied similar code to the MS Box. It did not work. Is this another caveat of MS boxes? 

As a test I used just 2 conditions to test:

The expression: starts-with(xdXDocument:GetDOM("ClassInfoForEnrollementForm")/dfs:myFields/dfs:dataFields/d:SharePointListItem_RW/d:Class[../d:ID = current()/dfs:dataFields/my:SharePointListItem_RW/my:Class], "CADLP Cadence Template Builder")

The expression:  dfs:dataFields/my:SharePointListItem_RW/my:Epic_x0020_Depts_x0020_HC/Value = ""

When I select  a CADLP Cadence Template Builder class from the Class dropdown box, it does disable the Submit button, but once I check a value in the Epic Depts MS Box, it does NOT become enabled, and it should. So I presume I may need to reference a null value in the MS Box some other way?

I believe I figured out the MS box issue. I had to change the 2nd condition to: All occurrences of Value are Blank. Now the box re-enables once I check a department.

Hilary thank so much for your time and sticking with me to the end. I so appreciate it!
