Thanks for your reply ... unfortunately, we have just started
customizing/using Sharepoint & our IT resources are tied up with other
Sharepoint issues that take higher precedence ... bottom line, they won't
be
able to get to it for months.

Any way to do what I want from within Excel? Even just the 1st piece
would
be a big help to us.

it
up if you are on a business network.

We have a spreadsheet used by multiple people from within MS
Sharepoint.

1st ... I'm looking for a way to generate a message that tells the user
that
someone else is in the spreadsheet as soon as they open it. My current
plan
is to tell them it's in use & to enter their data then use File Send
to
to
send it to me for later posting.

All files automatically appear with a "READ ONLY" indicator when we
open
them from within Sharepoint, so I can't rely on that as an indicator.

2nd ... I would ultimately like to create some kind of temporary
collection/storage sheet or form that allows users to enter their
information
& save it individually until it can be merged with the real
spreadsheet.

Preferably something that can be accessed by multiple users & generate
individual docs/sheets -- like Word users clicking a template &
generating
an
individual doc off the template instead of the template itself.

Does anyone have any idea how I can do either of these things? I've
written
some macros & created user forms in Word but nothing in Excel yet.

Thanks for your help!
