Combining two IF functions in one cell using Excel 2010

Question

I have these two IF functions that work correctly on their own. I need to combine the two into one cell but can't seem to get them to work. Any help would be appreciated. And thanks in advance.

Screen capture 1

=IF(AND((D5="Intel"),(Z5="Not Attempted")),"Not Attempted")

Screen capture 2

=IF(AND(OR(D5="Pilot", D5="Sensor", D5="Admin"),(Z5="Not Attempted"),OR(C5="E-1",C5="E-2",C5="E-3",C5="E-7",C5="E-8",C5="E-9",C5="O-4",C5="O-5",C5="O-6")),"Not Required", "Not Attempted")

I've tried the following combos without any luck.

This one results in screen capture 3

=IF(AND((D5="Intel"),(Z5="Not Attempted")),"Not Attempted")=IF(AND(OR(D5="Pilot", D5="Sensor", D5="Admin"),(Z5="Not Attempted"),OR(C5="E-1",C5="E-2",C5="E-3",C5="E-7",C5="E-8",C5="E-9",C5="O-4",C5="O-5",C5="O-6")),"Not Required", "Not Attempted")

This combo results in a #VALUE! Error in the cell:

=IF(AND((D5="Intel"),(Z5="Not Attempted")),"Not Attempted"),IF(AND(OR(D5="Pilot", D5="Sensor", D5="Admin"),(Z5="Not Attempted"),OR(C5="E-1",C5="E-2",C5="E-3",C5="E-7",C5="E-8",C5="E-9",C5="O-4",C5="O-5",C5="O-6")),"Not Required", "Not Attempted")

And this screen capture is me manually updating the cells to show what I need them to show, screen capture 4

Answer 1

Those are really long IF if you ask me!

But if I understand what you're trying to do...

It will be either this:

=IF(AND(OR(D5="Pilot", D5="Sensor", D5="Admin"),(Z5="Not Attempted"),OR(C5="E-1",C5="E-2",C5="E-3",C5="E-7",C5="E-8",C5="E-9",C5="O-4",C5="O-5",C5="O-6")),"Not Required", IF(AND((D5="Intel"),(Z5="Not Attempted")),"Not Attempted"))

Or this:

=IF(AND((D5="Intel"),(Z5="Not Attempted")),"Not Attempted", IF(AND(OR(D5="Pilot", D5="Sensor", D5="Admin"),(Z5="Not Attempted"),OR(C5="E-1",C5="E-2",C5="E-3",C5="E-7",C5="E-8",C5="E-9",C5="O-4",C5="O-5",C5="O-6")),"Not Required", "Not Attempted"))

It depends on what you want to check for first.

EDIT: After reconsidering the formula, maybe this would be better:

=IF(AND(OR(D5="Pilot", D5="Sensor", D5="Admin"),(Z5="Not Attempted"),OR(C5="E-1",C5="E-2",C5="E-3",C5="E-7",C5="E-8",C5="E-9",C5="O-4",C5="O-5",C5="O-6")),"Not Required", IF(Z5="Not Attempted","Not Attempted"))
