Hi everybody!

Could you please help me with the following problem.
I have recently installed Windows XP and MS Office 2003. Now I am trying to run my old Excel worksheets with external
DLL functions, but they don't work - Excel is constantly throwing out "#value!"... I'm sure that my code is correct - it worked in Office 2000
with Windows 98. What could be a problem? In my opinion, there might be security restrictions imposed by Windows XP or Excel on using external dlls or Excel is missing some add-ins.
Could you please suggest me how to resolve this problem?

Thank you in advance!
