Conditionally Show_If a File Column has an attached file

[rbahne]

Hi I have a File Column called Supporting Documentation. Where a user can attach a file... 
I want to include a virtual column linked to a google sheet to add an infinite number of additional files. However, I only want to offer the Additional Documentation if there is a file added in the Supporting Documentation field first. 

I would think that this would work: SHOW_IF > ISNOTBLANK("Supporting Documents")
But it definitely does not 😞

Any ideas would be appreciated!

You should add the column name using square brackets.

ISNOTBLANK([YourColumn])

Thanks so much SkrOYC > worked like a charm. 
I will try to give you a harder challenge next time!!!
