New Post: Cascading lookup - child drop-down not filtering

Hi again Charles,

getting a SharePoint error:
Error
Failed to get value of the "Course" column from the "Lookup" field type control. See details in log. Exception message: Input string was not in a correct format..

I tried a few things: used GUID for relationshipList, tried changing the FieldRef Name in the myQuery line to 'PCYC Club' as well as 'PCYC_x0020_Club' but the Course drop down remains empty. Unlike Ned Flanders' parents I did try something but I'm all out of ideas...

I note that we're not using the static name (PCYC_x0020_Club) in the new script? Stab in the dark I will admit.

Thanks

Mark
