I have values in column Y, and a number of different names in column C. I
would like to create an average of the Y values for a select group of the
names from C. I have tried the following two ways and get a #DIV/0! error
both times. Any help is appreciated!

{=AVERAGE(IF(($C$2:$C$60000="Jane")*($C$2:$C$60000 ="John")*($C$2:$C$60000="Joan")*($C$2:$C$60000="Je an"),$Y$2:$Y$60000))}

{=AVERAGE(IF($C$2:$C$60000="Jane",(IF($C$2:$C$6000 0="John",(IF($C$2:$C$60000="Joan",(IF($C$2:$C$6000 0="Jean",(IF($Y$2:$Y$60000))))))))))}
