I have a worksheet with some macros needed for several other worksheets. I
have added it to my XLStart folder, however whenever I try to set a reference
to the startup file programmatically I receive an "error loading dll"
message. I have the workbook saved as a .xla, and I can open it correctly
manually. However, whenever I open it using the Workbooks.Open command, it
opens as Filename1, appears in my reference list as "Unsaved: FileName" and
I can not access the various modules in the code.

What do I need to do to make the code in this workbook available to other
workbooks?
