I have a cell that references a cell on another tab, so what ever is typed in
a cell on the first tab gets transferred onto the second tab. The problem is,
that when the first tab cell has nothing in it, the second tab shows a value
"0". I would prefer that it just remains blank like the first tab.

Thanks
