Calculating Totals - Please Help

[brian0721]

Hi, Im new at the whole access thing, but I seem to be doing alright. Here is my problem. I am making a database that stores information on loan closings. It stores: open date, closed date, loan amount, income, loan officer, and a few other categories. there are 4 different loan officers. i need to make a report that will calculate total loan amounts and income in a few ways: monthly, quartely, and yearly. I am having great difficulty with this and would appreciate ANY help. THANK YOU in advance!
