Posted on by scorpio24 278
Hi experts, please help me detect duplicate selected items from 2 different combo box (DataCard in Form)
Please see screenshot below for context: I just added the visibility of the label with: 
endorsers.Selected.DisplayName=approvers.Selected.DisplayName
 
however not working properly if there are 2 or more same names. Note that the Data Cards are multi-select.
 
 
Thank you in advance!
