I have a worksheet where the first column contains a special code
specific to each product we sell, containing a code for 1) the
territory where it's sold; 2) the vendor; 3) the product name; etc. I
am trying to figure out a way to create a sumif formula (or other
formula if necessary) to only sum, for example, values where the
vendor is XYZ. Here's an example:

A B

1 C-SRS-TMN-ARBYS-5 50
2 C-SRS-SLF-TESTY-1 75
3 C-SRS-INC-CRASHY-3 100
4 C-SRS-TMN-TESTY-3 50
5 C-SRS-TMN-TESTY-4 80

So, let's say I want to sum everything that has a Vendor of "TMN" (the
third set within the code). The result should be 180 (B1+B4+B5). Or,
if I want to sum everything has a title of "Testy" (the fourth set
within the code). The result of that should be 205 (B2+B4+B5). Or,
even more complex, anything sold by TMN with the Title of "Testy" (130
= B4+B5).

I designed this whole coding system thinking I could do a combination
of SUMIF and the FIND/LEFT/MID functions, but realized after
implementing it that that just wouldn't work. Any help would be
GREATLY appreciated!

Thanks!
