In an Excel spreadsheet I have created a formula which includes blank
cells,
which gives me an error. If I change the blank cells to "0" than the
formula
is accepted. The spreadsheet is large and would be very time consuming to
go
through and add a zero to each blank cell. Is there a way to change the
cells
automatically?
