I'm hoping someone will be able to help

I am using a sumproduct formula and I need it to find the all the cells containing the word Pauline inside the cell.
I have tried the below formula but excel will not accept it as it contains too many arguments

=SUMPRODUCT(ISNUMBER(SEARCH("pauline",January!F3:F501),--(January!$K$3:$K$500='Environmental Totals'!$A$36)))
Is there another way of getting this formula to work

Cheers
