Hi,
My question is - for a Ref range in the user form, I want to set it up to only be able select from column A B and C. ( it has select ABC column at the same time, if missing any column, error message will come out, or select out of this range, the error message should also come up. )
I know how to set the range to all three columns, but I know don't how to ask for " must select from all three column?"
Thank you in advance for any help. !!
