I've tried to add the xls extension and mime type to the attachment manager. The file uploads but when I click on the attachment then I do not see a spreadsheet but rather a big mess. :o

I'm guessing that I do not have the mime type set correctly. I've tried several settings and have it presently set to application/x-msexcel. Any ideas on what I'm doing wrong?

Thank you.

OK,

The correct format is:

Content-type: application/vnd.ms-excel
