Add filter to schedules not working

Hello, all, so i looked on this site for how to add filters to schedules, and best confuguration that looks like it should work on dynamo 1.3.4 is how I made it below. However I get this error message and I dont know why. I dont think I should, based on other peoples posts. Please advise.
Thanks!

This might be a version thing. I’ve had a quick look, and on mine it’s ‘Equal’ rather than ‘Equals’. I’m not sure what version you’re running for Revit, but if it’s a newer version of Revit (e.g. 2020) with an older version of Dynamo (1.3) then the drop-down will be calling up a name that doesn’t exist and producing the error you see.
