Excel Macro to allow adding rows

I'm not sure what this is called (possibly dynamic named range) so I will try to explain. I am trying to update a macro that was written by somebody else. In the macro he used row numbers. I have added rows within the referenced area and now the macro pulls information from the wrong rows. I want to change the macro to allow for more rows whenever I feel like we need to add them. The piece of the code that I want to update is below. If I change the row numbers, it works properly, but I need them to allow for movement. I'm not sure how the rest of the macro uses this piece, so if I need to post the rest of the macro or the actual document, please let me know.
