When I have a formula in a cell, how can I make it come up blank?

[Vi]

Example, I have the formula e2+e3 in cell e4. I have data in cell e3 but
nothing in cell e2. I want e4 to be blank instead of putting in a zero.
Thanks.

=IF(E2="","",E2+E3)

Basically this does the check. Especially important if your formula has
divides.

Try this in E4:

=IF(OR(E2="",E3=""),"",E2+E3)

Hope this helps.

=IF(E2="","",E2+E3)
or
=IF(ISBLANK(E2),"",E2+E3)
