Help with Sumproduct

Can you please help with the attached for me.

I have downloaded the CRM spreadsheet but, when using even the default you send through, if I make Opportunity Tracker F4 (Business Name) the same as Communication Log B6 (Company) the email activity from the Communication Log does not carry through to the Opportunity Tracker tab.

Opportunity formula: =SUMPRODUCT('Communication Log'!E$5:E$7=1,'Communication Log'!B$5:B$7=F4)

The Communication log does have 1 in F4 representing an email.

Can you please test the sheet and advise what the formula should read?
