I have a formula that I need to use in two different ways.

The first it needs to ignore the blank cells in a range, and sum two other ranges that meet a single text string criteria in each range. But one of the text strings is a combination of text with a dash and then a letter and a number I just need the first four characters. I tried the formula in a few different ways with no luck usually getting a "0".

=SUMPRODUCT('SCHEDULE WEEK ONE'!$Q$5:$Q$1300="")*('SCHEDULE WEEK ONE'!$V$5:$V$1300=D8)*('SCHEDULE WEEK ONE'!$U$5:$U$1300=B8)

D8 is the text string that, four or more letter and then has a dash followed by a letter and number. The formula needs to ignore the "" in the range Q5:Q1300 then check the sum the other ranges.

Thank you for your help
