Sumif formula. I need to somehow put a loop on the criteria or something...

The formula is sumif(range, criteria, sum range). The problem I am having is that I have about 20 criteria to select, and sumif is designed for one criteria. I know that I can type the exact same formaula in and have something like this...

=SUMIF(D25:D107,Variables!A6,F25:F108) + SUMIF(D25:D107,Variables!A7,F25:F108) + SUMIF(D25:D107,Variables!A8,F25:F108) + SUMIF(D25:D107,Variables!A9,F25:F108)+ SUMIF(D26:D107,Variables!A10,F26:F108)+ SUMIF(D26:D107,Variables!A11,F26:F108)

This is OK for a few variables but some formulas have multiple criteria in excess of 15-20. the other thing is that the criteria list will grow over time as more variable are added, and instead of changing the formulas throughout the spreadsheet, I would like to have a big range that I can slowly fill up as I go along

The ideal situation would be if I could put a range in ( ie A6:A30) and then when I get a new criteria I just add it to this range. This will make administration eaaseier by giving me one location to update data.

I will show you an example.. I want to calculate the amount of petrol I use based on three criteria - BP, Shell, Caltex ( the criteria being petrol stations that come up on my bill).

Column

A/ B / C/ D

Row / description / Amount/Variables

1 / Shell Petrol / $10/Shell

2 / Cat Food/$13/BP

3 / BP Store/$24 / Caltex

4 / Dog Food/$23

5/Shell Petrol / $98

6/Caltex Petrol/$31

7/BP stuff/$30

8/Shell Store/$70

What I have been doing is this...

=sumif(B1:B8,D1,c1:c8) + sumif(B1:B8,D2,c1:c8) + sumif(B1:B8,D3,c1:c8)

If I could somehow get the formula to choose the whole column D as the criteria range and get the 'sum if' to somehow loop so it goes down the d column and does the same calculation, but just changes the criteria variable each time, then instead of changing the formula, I could just add to the D column each time I had a new criteria I wanted to check.

I looked into DSUM and Pivot Tables. DSUM seems to work well with numbers, not variables and Pivot tables did my head in, especially seeing I know that there is a way to do this in a formula based way..
