Hey Richard - Great to hear from you mate!!

Which email client are you using? If you are using an installed email program such as Outlook, Outlook Express, Thunderbird, etc. these are the methods you can use:

1) Open an email as per normal. In the menu items look for 'Attach'. Click on that and then browse to the location of your Excel file. Click on that once to highlight it and then click on 'Open'.
2) In the excel document click File - Send To - Mail Recipitent (As Attachment).
3) Navigate to the location of the saved Excel file. Right click on that file and select 'Send To' and then 'Mail Recipient'.
Don't forget to select the recipients!

If you are using any sort of webmail such as Hotmail, GMail, etc. only the first option is available.

Cheers mate.....JIM
