hi ! thanks for your reply....you were indeed right...there is quite a
bit of VBA code behind this spreadsheet. Most of it is password
protected so i can't see how they've actually programmed it..... This
probably isn't the right forum to ask whether someone has any idea how
to program this in vba ? I know some VBA but this goes beyond my
knowledge..... Tx all!
