This one is a strange problem. To begin with we have developed many Excel templates( Excel 2000 with the latest service packs) with VBA modules and one of those modules is a VB class that uses mid$. These templates all work find on Win 2000, Win XP, Win 98, Office 2000 and Office 2002 except on this one persons PC which is an Office 2000( latst service packs) and Win 2000 with latest service packs. On this person PC we get an error message that the library for Mid$ cannot be found. Now what makes this even stranger is that on this very same PC if we create a new Excel template and make use of Mid$ it is found with no problem. We also have re-installed Office and still this is happening. Anyone have any idea what is hapening?
