I RECENTLY UPGRADED FROM EXCEL 2000 TO EXCEL 2003. IN EXCEL 2000, THERE WAS
AN ENGINEERING FUNCTION CATAGORY AND IN THIS CATAGORY THERE WAS AN
INTERPOLATION FUNCTION. I USE THIS FUNCTION ALL THE TIME AND WHEN I TRIED TO
USE IT IN EXCEL 2003, IT SAID IT WAS UNDEFINED. I DO NOT KNOW IF ANYBODY OUT
THERE KNOWS WHERE I CAN FIND THIS FUNCTION. IF SO, PLEASE HELP.
