Input must fall within specified range error

How do I fix the “Input must fall within specified range” error?

The error occurs for my “Rent” category.

Can you reference the article below. There may be a problem with the data validation formula for your categories. Can you reference the below article for a fix.

I also have this issue. That article didn’t seem to help. Unless I did not follow it correctly.

Ok I followed the steps again and it seems like it’s all ok now.

Still not sure what I did wrong the first time, lol.
