sue's mom, here's
one example of posts that explain pivot tables you can find by searching the lending forum using 'pivot' for your search word. I'm hooked so I've made several posts advocating their use!

I also googled excel pivot and came up with a number of good sites that explain the how and why's of pivot tables.
This site even has a demo you can watch. Scroll down on the right and look for pivot table heading, then click on pivot table demo.
If you'd like help setting up a pivot table for either editing or analyzing your HMDA data, feel free to pm me.
