VBA Stuff- Weight Watcher Spreadsheet

I have a Weight Watcher spreadsheet. I enter the Calories, Fat and Fiber and I get the # of points for that food. Then I keep put those points into the lower part of the spreadsheet where I track what I eat, and Excel does my simple math for me. What I want to do is keep a list of my foods, and their point value in my spreadsheet. I would like to be able to put the food name in Cell A1, the WW points in BI, and then be able to click a button with a macro that takes those two pieces of data and add them to bottom of my food list. I don't have a food list yet, I would assume I can just put it on sheet 2. I then want to be able to use lists in my cells to choose the food in the future. I need to be reminded how to make "dynamic named ranges. Today, I just need to know how to write the macro to copy and paste those two cells in the first open row at the bottom of my food list.
