OLE32 error

I am using vb to build and display a spreadsheet in excel using "create object"
for the excel application. I recently added a module to the app that contains a dynamic macro and now when I try to close VB, excel generates an OLE32 error.
I am setting the objects to "nothing" on close. I was wondering if I am missing an ole initialize command or something. I was able to close with no error until I added the module with a macro. Thanks
