Hello,
I need to enforce unique values for some columns in a Sharepoint list but cannot find a solution that is working. This columns are formatted as Date and as Person. OOTB permit only one column at a time to be unique.
I find an article bellow using this javascript code that is placed on the newpage.aspx but cannot make it work.
This is the code that i try to modify , from site bellow. I also made a list with exact this fields ,but it's not working. Can you tell me what i do wrong?
