I have used the following formula in a few of my sheets, and it usually works. But sometimes I get a Blocked Error - can someone interpret the problem for me?

=IF(NOT(ISBLANK([Closed Date]@row)), "Closed", IF(AND([Due Date]@row < [Todays Date]#, NOT(ISBLANK([Due Date]@row))), "Overdue", "Open"))


  • Hi Karen, I'm having the same issue since today. I'm not sure what happened because everything was working before!

    Hi @Karen Bruer,

    #BLOCKED errors occur when your formula is looking at a cell/column with another formula or value it can't read. I would check each column your formula touches and make sure there isn't any data that is invalid. I've found them sometimes hiding near the bottom of my sheet, or in-between rows. You may stumble across #N/A, or #VALUE in your Closed Date, Due Date columns.
