The only reason why that might happen (assuming it is working somewhere else),
the object isn't return. So connect() constructor couldn't return the object.
To read the error message from DBI, you'll have to read $DBI::errstr:
my $dbh = DBI->connect(dsn, login, password) or die $DBI::errstr;
The error log says,
Can't call method "do: on an undefined value. . .
But the EXACT SAME code works on another script I'm running. I don't see any
reason for it to suddenly have a problem. What does this error message MEAN?

I overcame this by adding to my php script, something that goves the
user the results, summerised, of what they added to the database, thus
when hitting refresh, it just refreshes the results of what the php
script returned, not what they submitted.
My php script is below.

OTOH, if you use mod_perl, *all* scripts are cached. That way you can have
a single script per function, which makes each smaller and simpler to debug.

Cindy, read my reply to this. You are mistaken. There is actually a way
to make a single script do all kinds of different operations. I have
single scripts that show a list of records, add a new record, update a
record, and delete a record, all in the same script. This is more

You need to have your script operate in different modes. You do this by
passing an argument when you call your script to tell the script what it is
supposed to do. So in this case, if the script is called with out any
arguments, it will display the form, as follows:
