I am creating a template with multiple columns that will be populated by
others. Some of these columns have specific character limitations--in these
cases I'd like to prevent them from going over the character limit. I've
considered using validation, but there is an excellent chance that some of
the columns will be populated by copying/pasting, in which case validation
doesn't help. I thought vba might be the best bet. What I'd love to have is
this:

If the person types or copies a value that exceeds the character limit, I
would like a general message to display saying something like, "You have
exceeded the character limit. Entries that exceed the limit will be
highlighted and truncated." Then I would like that to happen--that is, to
have their entry truncated to the max character limit, and that cell
highlighted. I would like to have this work whether they pasted in one cell
or multiple cells at a time. Does anyone have any ideas how I could
accomplish this? Any guidance would be appreciated.

Thanks,

Jeff
