Vlookup question

I am setting up a personal finances budget in Excel. One worksheet is committed to being a "transactions" worksheet that has columns for: DATE/CHECK NUMBER/DESCRIPTION/DEBIT/CREDIT/BALANCE.

I have another worksheet that is being used as a budget worksheet. I want to be able to pull information from the "transactions" worksheet AUTOMATICALLY. I want to be able for a particular cell to look up the SUM of a particular "description" within a range of dates (such as within the month of march) from the "transactions" worksheet.

I am pretty sure its going to have to be a vlookup of a vlookup but I am not sure.. can anyone help?

Thanks so much.
