I have a multi-sheet workbook (Excel 2003) that has a group of the same
three command buttons on the top of each worksheet. Each button is linked
to a separate macro. One user reports that all 3 buttons perform the same
function on one specific worksheet. The functionality works fine when I
test it. Any thoughts? Thanks!

Your client likely changed the assignment of the buttons. Right click
over each Command Button and ensure that the link has not changed.
