Auto Refresh Macro When Cell Changes

[Ajweis01]

I am going to be leaving this company soon to go back to college, but I want to make a macro so that the next person who takes my position can do my job easier. I want it so when whoever edits a range of data, it will automatically refresh all of the pivot tables in the workbook. For example. I have data entered from A1-L25015, and say the person enters something in the row below that, I would like the workbook to automatically refresh.
