Hi,

I'm really new to excel and am having a hard time trying to complete an
assignment for my teacher. Could anyone tell me what is wrong with this
formula?

=IF(AND(ISBLANK(F6)),(ISBLANK(G6)),"", (H6+G6-F6))

What I want to do is in a simple accounting worksheet calculate the data
in two individual cells to complete a running balance in a third cell,
but if the first two are empty, I want the third cell to be blank, too.

Thanks.
