Hi

can someone help me with a countif function

this one works - =if(countif(D2:D23,A15)=1," ",ROW())

however if I use more than one range it doesn't allow the formula

I tried to incorporate D2:D5, E5, F4

I tried this - = if(countif(D2:D5, E5, F4)=1," ",ROW())
it doesn't allow the formula

any help

thanks

andrewm
