Convert to Column Formula - column formula syntax isn't quite right

markj1

I am trying to populate project number from line 1 into line that has any text in To-Do column. The single line works but when I try to convert column formula I get "The column formula syntax isn't quite right, see our help article

I have tried it both

=IF(ISBLANK([To-Do]@row), "", [Project Number]$1)

=IF(ISBLANK([To-Do]@row), "", [Project Number]1)

@markj1 You must change your $1 or 1 to @row. Column formulas can ONLY reference their own row or a full column, not a random cell.

Thank you @Matt Lynn-PCG. That's a bummer.

Do you know of another way to reference another row?

I want the Project number of the row to copy and paste project number of row 1 when using that row.
