I need some help with a formula that is partially working. I've tried a few ways to code this, but gets an error so I'm probably missing something...
During our intake process using Smartsheet a form can be filled out by multiple people. To my knowledge, there isn't an easy way to prevent multiple submissions for the same entry/customer... such as a pop-up message like, "there is already an open entry in progress".
So, I have a Duplicate column that should have a Checkbox marked TRUE when Customer Code value is Duplicated more than once AND the Status for both is Open (i.e. "Not Started", or "In Progress", or "Watch")
If one entry is Closed (i.e. "Completed", or "Terminated") and the other is still "In Progress" it shouldn't be marked as a Duplicate. In the example below (see screenshot), AGN is duplicate because both are "In Progress". However, ACC shouldn't be checked because only one entry is open ("Watch") and the other is "Completed".
Here's the formula I'm currently using in the Duplicate cell, which is only partially working:
=IF(AND(COUNTIF([Customer Code]:[Customer Code], [Customer Code]@row) > 1, Status@row <> "Completed"), 1, 0)
