Not sure if this should be in User-forms or not - but I suspect with my lack of Word knowledge, this may be an easy one...

I have a simple label document set up so that, when completed, it prints out correctly to the labels in a specific printer.

The trouble is that people will copy and paste an address from, say, an A4 document into the label document and therefore mess up all the settings.

I've had a look to see how I can protect the format somehow but so far have drawn a blank. Any ideas? Thanks.
