Sum Frequency with Wildcard

[MrMaker]

Morning all,

I've got a working Sum Frequency formula which counts unique matches.

=SUM(--(FREQUENCY(IF((Driver!$A$2:$A$1973='Data Selection'!$A$1)*(Driver!$G$2:$G$1973="No"),MATCH(Driver!$D$2:$D$1973,Driver!$D$2:$D$1973,0)),ROW(Driver!$D$2:$D$1973)-ROW(OFFSET(Driver!$D$1,1,))+1)>0))

It works well but I need to amend the ="No" (in bold above) part so that it looks for No as a Wildcard instead of a direct match.

I've tried making it "*No*" but this doesn't work

Any suggestions?

Thanks in advance

try
isnumber(find("No",Driver!$G$2:$G$1973))

With a slight change to the match range you should be able to remove some unnecessary functions from your formula as well.

=SUM(--(FREQUENCY(IF((Driver!$A$2:$A$1973='Data Selection'!$A$1)* ISNUMBER(FIND("No",Driver!$G$2:$G$1973)),MATCH(Driver!$D$2:$D$1973,Driver!$D$1:$D$1973,0)),ROW(Driver!$D$2:$D$1973))>0))

I've included @shaowu459's suggestion in the edited formula above. Note that there are potential problems with this method depending on the data in column G. FIND is case sensitive, so it will pick up rows with "No" but will miss "no". To count rows with "no" as well, you would need to use SEARCH instead, but that is not without potential problems. FIND will also count rows containing words like "Nose", while SEARCH would see "Abnormal" as a valid match.
