Greetings all. I have a workflow where I have a multi-value token that is populated with PO numbers. After the token is populated I need to go through and check to see if any of the PO numbers are duplicates and remove them. I currently have the following:

I first create a new token that is empty (MultiPO). Then for each value in the multi-value token that contains all of the PO numbers, I check to see if the current PO Number value Is In MultiPO. If not, then it adds the value to the MultiPO token and loops back through.

My problem is that it works for the first value that is a duplicate, but not for the rest of the values. I am guessing that I just have my Operator Text incorrect. Instead of 'Is In I am guessing I need to use something else to check all values in the multi-value token. I have also tried equals and that doesn't seem to work correctly either. Can anyone point me in the right direction?
