I want to write an equation that says if E20, E30, E40, E50, and
E60 then I would take C2*E2, plus C3*E3, plus C4*E4, plus C5*E5, plus
C6*E6. So for example C2=400, C3=400, C4=450, C5=500, C6=550, E2=200,
E3=0, E4=100, E5=0, and E6=150. What I want to get for a total is
207,500. Taking C2*E2+C4*E4+C6*E6. Can anyone help me?

Your description does not make sense with your requested answer.

In your example, you "AND" e2:e6. Since at least one of them (actually two: E3 and E5) is not 0, then, logically, you should not be executing the multiplication to obtain 207500.

In other words, you are NOT indicating, by your example, that you want to "AND" E2:E6 else your result should be zero.

If what you really want is an equation that says if E20, E30, E40, E50, OR E60, then ...

Try: =SUMPRODUCT((E2:E60)*C2:C6*E2:E6)

However, if E2:E6 can never be less than zero, you could simplify further to:

=SUMPRODUCT(C2:C6*E2:E6) Since 0*some number will always be 0
