If you want to correlate if each cell in column A is equal to 1, you'd use:

=IF(COUNTIF($A$1:$A$100,"=1")=COUNT($A$1:$A$100),C ORREL($B$1:$B$100,$C$1:$C$100),"")

If there is a cell in column A that is not equal to 1, the above statement
returns an empty cell.

Hope that helped!

I'm trying to use CORREL of 2 columns of data which is based on a conditon of
another column of data. Something like -

IF($a$1:$a$100=1,CORREL($b$1:$b$100,$c$1:$c$100))

Thanks in advance!
