Multi-Row Formula Tool Issue

Question

I am having Trouble getting this tool to work. I need Category A dragged down to Category B and Category B dragged down to Category C and so on. I have followed the step by step instructions on the community page and it is still not working Properly. I have attached the workflow for reference. This is the expression I am using: IIF(isnull([Category]),[Row-1:Category],[Category]). Can somebody please help me out with this?

Thank you,

Mike

We're unable to run the workflow because the input files were not included. To include these file, use Options > Export Workflow and attach the .yxzp file here.

Without knowing what the contents look like, a general suggestion would be to use "isempty(" rather than "isnull(" because the isempty logic covers both null and empty string fields.
