send email from Excel using outlook template

I am trying to use excel to create an outlook message based on a template.  I am not a programmer but have put together macros based on postings I've found online.  I'll post the current macro code.  It's only creating the entry on the last line from the excel sheet.I am trying to use excel to create an outlook message based on a template.  I am not a programmer but have put together macros based on postings I've found online.  I'll post the current macro code.  It's only creating the entry on the last line from the excel sheet.
