Error handling

P: n/a
I have an intranet site that connects to an access database using ASP
(Javascript).
Currently, when an user attempts to enter a duplicate value into the
database it is rejected and the user is redirected to a custom
message generated by the ODBC driver (I think). How can I change this so
that the user is redirected to a message that I customise myself?

OK, here goes.

I am new to coding in Javascript. The page was created in Dreamweaver. Here
is the code. If you can help I would be grateful.
