I know sumproduct won't work with wildcards, but i need to use something that
allows me to do this.

=SUMPRODUCT(--(Sheet1!$C$2:$C$30000=1),--(Sheet1!$D$2:$D$30000=""),--(MONTH(Sheet1!$I$2:$I$30000)=F2),--(YEAR(Sheet1!$I$2:$I$30000)=H2))

The above works fine thanks to a lot of help from Bob. However I now need to
expand the formula so that it will look for the word TECO or CLSD in a cell.

The cell can contain data in this format

TECO PCNF PRT NMAT PRC SETC

I have tried a number of things to no avail. Help appreciated.
