Function problems, please help

Hi

I'm having a problem with a function that I can't get right.

I'm currently using the following:

=IF(E16=F16,"1","0")

This works fine in that when there is data entered into the cells, I get the correct result I require.

The problem I'm having is that I need to return a result of "0" when there is no data in cells E16 or F16. At the moment, when the cells are blank, I still get a return of "1".

Could anyone help please?

Many thanks

Mama

try

=if(or(isblank(e16),isblank(f16),e16<>f16),"0","1")

PERFECT.

Thanks very much!
