Thank you for looking at my question,

I have been sent a spreadsheet that contains a formula with syntax I've not seen before and hope somebody will explain it to me. The formula as it appears in the cell is below.

=SUMPRODUCT(--(DeliveryCountry=$A3)*(--(OrderOrigin="Sales")*(LEFT(Description,2)="FR")*--(LEFT(Type,3)="XL5"))*(Quantity))

Tell me please what does the double minus sign signify?

It's to coerce TRUE and FALSE values into 1's and 0's

I found out what's happening now, it's acting like a 'WHERE' condition.

=SUMPRODUCT(--(DeliveryCountry=$A3)*(--(OrderOrigin="Sales")*(LEFT(Description,2)="FR")*--(LEFT(Type,3)="XL5"))*(Quantity))

SUMPRODUCT WHERE the content of the cell(s) in column DeliveryCountry =  the contents of ref A3 (in this case Germany)
                           WHERE the content of cell(s) in column OrderOrigin = "Sales" etc
