I have created a spreadsheet that is divided up into 3 sections... It looks
something like this: (I'll use customers as fake data to help make it easier
to understand)

CUSTOMER TYPE 1 INFORMATION
Charlie Brown 1234 Anywhere Drive Nowhere, ST
Sally Brown 5678 Nowhere Drive Anywhere, ST
Linus VanPelt 9101 Somewhere Drive Somewhere, ST

CUSTOMER TYPE 2 INFORMATION
Lucy VanPelt 4321 Anywhere Drive Nowhere, ST
Peppermint Patty 9876 Nowhere Drive Anywhere, ST

CUSTOMER TYPE 3 INFORMATION
Snoopy 5678 Somewhere Drive Somewhere, ST
Woodstock 4567 Nowhere Drive Nowhere, ST
Schroeder 2345 Anywhere Drive Anywhere, ST
Marcy 9635 Overthere Street Overhere, ST

Now what I have is a row or 2 of empty rows available for when users need to
add new data. However, they add new data frequently, and will be needing to
add rows often. I dont want to just add a bunch of available empty rows
between the 3 different sets of information, because I do not want it to
print with a bunch of empty lines. Also, I dont want to add a bunch of empty
rows and just hide them, because users may not know that there are hidden
rows available, and some do not know how to unhide rows. My 2 solutions to
this problem a

1.) I need a way to prompt someone to ask them if they need a new row added
under "whichever section they need" when there is no longer an available row.
The kicker is that I need to keep on adding rows to the 3 different
sections.... so anytime the number of available rows runs out for the
selection they need, then it asks them if they would like to insert a new row
under section "Customers 2" (prompted because the last available row in
Customers 2 has just been used). A problem I see with this is that if
someone uses up the last line, and are finished in the worksheet, and they
get the prompt asking them if they need to add a new row under Customers 2,
they will naturally say "no' because they are done. But when the next person
enters that spreadsheet, they might need a new row under "Customers 2", and
they would need the prompt so that they could enter a row... Make sense?

2.) My other solution would be to create a macro that would always allow
for about 3-5 lines of empty rows, available for use under each section. If
someone is typing in one of the lines, as soon as they begin typing in that
row, excel recognizes that it will have one less available row, so it will
automatically add a new row to compensate for the other row being used.

Any help you can provide will be EXTREMELY useful!

Thanks!
