You could put in an equation where NA() is entered if the values entered in
A-C are blank. You could then conditionally format column D so that NA()
is formatted in the same color as the background.

I have 4 cells, A-D. Cell D is the "sum" cell. Cell D will show a "0"
on the spreadsheet if nothing is inputed into any of the 3 other
cells.

How do i write the formula in cell D so that the "0" does not show on
the spreadsheet until numbers are put into any or all of cells A-C?
