New Post: Cascading Displays Duplicate Choices When Info Is Required

Greetings

Background:
I have a parent list (PL) and a child list (CL) I use as the source for lookup categories to a document library in SP 2010. SPServices suites my needs perfectly for cascading the document categories.

Issue:
I have users that upload documents to the library without categorizing the document via selecting options from the PL and CL lookup columns. I modified the lookups to require the columns contain information.

Problem:
The CL column contains duplicate entries after selecting “Yes” to require that this column contains information. When the PL is “Yes” and the CL is “No”, all is well. When both are “Yes” I receive duplicate options in the CL. My CL is a small list and does not contain duplicates.

Please advise.
