Client is using Excel 03/WinXP. She has some code that uses the Solver. It
worked fine with Excel 2000 but now is giving : Compile error:
Sub or Function not defined.

The solver addin is turned on in Tools, Addins. We even readded the Solver
addin by navigating to the xla file to make sure it was looking at the
correct file. Macro security is at Medium and macros are enabled.

When we go into the References in VB Editor, we check the Solver
reference,
save the code but when go back into Excel, the reference is once again
unchecked. We even used the browse button here to locate the correct file
but
it still won't stick.

We've also checked the Analysis Toolpack and Analysis Toolpack VBA addins
and still having problems.

What else can we try???
