SUMIF no error, but returns '0' vs. actual sum

tere.pile42541

I'm using the Sum =SUM(CHILDREN()) to capture scoring of items by various teams, which is working great for each tool/category, but I want to now show a score by team (not just overall total by tool). 

=SUMIF(Tool6:Tool187, "Development", [Key factor]6:[Key factor]187) - this results in '0' (should be 35)

Summing a number in the Tool column / where 'Product' is found in Key factor column

I've tried variations of the above but get various errors.  I'm sure I'm overlooking the obvious but kind of stuck at this point.  thanks

According to the =SUMIF formula instructions found here:

You will want to put the range that has the criterion first, then your criterion and then your sum-range last. 

=SUMIF([Key factor]6:[Key factor]187, "Development", Tool6:Tool187)

Swapping those ranges should do the trick for you.

That was it, thought I had reversed previously but I think I neglected the [ ] in proper place.  Thank you
