IF ISNOTBLANK() Expression

[alhazen]

Dear All,

Need your help!

I have two column which are [report] as file type column and [status] as text type column. I put this expression in [status] column:

IF(ISNOTBLANK([report]),"Closed","Pending") 

So when users have uploaded the file, [status] column will change to "closed". But My formula it doesn't work.

Thank you.
