Hi SilverBear,
One of the great things about a Mac is how much you can get done by pointing and clicking. I think Wayne has your answer if you are just looking for your yearly totals for each catagory. It is just getting the formula in your table that is the issue. Everything is going to happen in the summary table. So lets point and click. This method should eliminate any need to worry about table names, etc..
Click in the B2 in the Summary Table, type "=" (no quotes). This brings up the function browser. You can find SUMIF there or just type it in after the =. If you typed it you need to hit return. You will see:
click "test values" if it is not darkened. then click column "E" in your INPUTDATA table. This chooses all of your "catagory" column as the place to look for matches.
click "condition" then click A2 in your Summary table. This says look for this in column E of INPUTDATA.
click "sum values" then click column "F" in INPUTDATA table.
Click the green check.
Grab the yellow dot and drag it to the bottom of your table.
So this formula says look in the "amount"column in INPUTDATA table for the value in the "catagory" column in the Summary table. when you find it add the value in the amount column.
The summary table tells you what you want to know ie how much you spent on each catagory during the year. It does not give you a running balance. We are not reporting back to the INPUTDATA table.
Hope this helps,
Quinn
