or to return nothing if it's false try this

=IF(AND(A1=1,B1=1),C1,"")

But if the OP wants an *empty* cell to remain empty, putting a formula,
or even the zero length string, in there makes it no longer an empty
cell. I think that's the root of the OP's question.

Hi,

You didn't say what you wanted if a1 * B1 don't = 1. Try this

=IF(AND(A1=1,B1=1),C1,"you didn't say")

or to return nothing if it's false try this

=IF(AND(A1=1,B1=1),C1,"")

When competing hypotheses are otherwise equal, adopt the hypothesis
that
introduces the fewest assumptions while still sufficiently answering
the
question.
