I have a situation where I want to apply the following argument

If A1 isn't blank and if A1 equals A2, put the value from C1 in D1.

If blank, enter ""

How do i combine or 'nest' the IF and the AND statements? Just for future
reference can I have several "AND's" in a row?

Thanks. I know this is "kindergarten" stuff but I can't find it in the
Excel help file and I need to set this up.
