Or you could combine both your formulas:

=SUMPRODUCT(--(A1:A100=1),(--(LEN(B1:B100)<LEN(SUBSTITUTE(B1:B100,"Dave",""))) ))

You can use a helper column. In Z1, enter:

=--(LEN(B1)<LEN(SUBSTITUTE(B1,"Dave",""))) and copy down and then use:

=SUMPRODUCT(--(A1:A100=C5),--(Z1:Z100))

i'm using the following formula to count the number of times a certain

this
formula so that it counts the number of times a certain value appears in
column A when the value in column B 'contains' the string Dave. Cells in
column B may contain something like Dave Smith (not just Dave).

=SUMPRODUCT(--(A1:A100=C5),--(B1:B100="Dave"))

Thanks in advance.
