excel 2007? save it as a macro-enabled file (xlsm) , or a standard workbook
I can't see how it would work as an add-in as i'd assume your code was
behind the active sheet?

more information please

In a workbook, I created coding that highlights a row when a cell is
selected.I saved the workbook as an Excel add in, .xlam. When I make the
add
in active, the add in doesn't work.
