It is both possible and the right list I don't have time to answer it in full and if someone already has great if not what you need to do is write some VBA functions. If you haven't wrote any Visual basic for application functions in Excel you might want to search out some tutorials on it, it would help you in what your doing greatly. When I get time I can try to respond but that might not be for a week.

I'd like to get an idea if array formulas will help me with a problem in Excel. First, I need to understand how they work. Secondly, here is the problem. In a work sheet, I have a column of data that I want to use for categories. On another sheet, I formatted a column so that it contains a drop down list that picks from the column in the first sheet. Here's the issue. I want to add to a total that corresponds to whatever category I happen to pick. For example, if the category in a cell is baseball tickets, I want to add to that total. If the category is clothes, I want to add to that one. I would very much like to avoid summing categories even if they have zero values. By that, I mean that I don't want to have to have a sheet that has a row for every single category. I just want to add to a category total if I pick it. Besides all of that, I want to roll up everything into daily, weekly, and monthly totals only for the categories I use. I don't even know if all of this is possible. If this is the wrong list to talk about this on, where can I take the question? Thanks.
