SUMPRODUCT formula with COUNTIF not working

What is wrong with this formula?

=SUMPRODUCT(--(Data!D6:D379=C15),--(Data!A6:A379="NVQ - Direct - ESF Enhanced"),--COUNTIF(Data!O6:O379,"*LATE*"))

I can get it to work for :

=SUMPRODUCT(--(Data!D6:D379=C15),--(Data!A6:A379="NVQ - Direct - ESF Enhanced"))

However I need it to also add the number of cells within that range containing the word "LATE". There might be some words before or after the word, however I still need to count the cells that contain this one word.

Any Ideas?

I am unable to post the spreadsheet. sorry.

Perhaps:

=SUMPRODUCT(--(Data!D6:D379=C15),--(Data!A6:A379="NVQ - Direct - ESF Enhanced"),--ISNUMBER(SEARCH("LATE",Data!O6:O379)))

(change SEARCH to FIND if it is to be case sensitive)
