I want to create a macro which sends JUST the active worksheet to a
pre-defined e-mail address (e.g. ") but instead of
just immediately sending it as the Mail_Worksheet sub want to do, I want it
to open up the Outlook dialogue box with the active worksheet inserted as an
attachment so that the sender can add a message prior to clicking 'send'.

Just to make it more awkward, the active worksheet contains several
'VLookups' which reference sheets (2) and (3) which will not be emailed but
the eventual recipient of the email must nevertheless see the values. I'm a
beginner and this is too hard for me I'm afraid. Any ideas for a code ?
