Thank you for your time. I am not sure I completely understand...the D2

200
reference is what is being averaged and the C cell references are the
criteria, correct?
I adapted it to this ...........
{=AVERAGE(IF('Sheet 1'!$B$1:$B$500>="10/01/2004",'Sheet
1'!$B$1:$B$500<="12/31/2004",'Sheet 1'!$D$1:$D$500))}
but am getting the same result regardless of the dates I put in. Can you
help with that?
I have also tried =AVERAGE(IF('Sheet 1'!$B$1:$B$500>="10/01/2004",'Sheet
1'!$B$1:$B$500<="12/31/2004"),'Sheet 1'!$D$1:$D$500) but it also gives me the
same result no matter what dates are entered. And thanks for the reminder
about the "control+ shift+enter"
