And what does your query produce when run straight against the database with an SQL command prompt?
How many records are there in the database that begin with '$name'? Does fetchrow_array return false? (If so, your resultset is zero rows.)
Also, I'm quite confused by the query. Do you have fields that are named $$$? (Double quotes are meant to quote table and field names in the SQL dialects I'm familiar with.)
Perhaps you mean:
my $sql = sprintf("... where CustomField = ? and Name like %s", $dbh->
+quote($name . '%'));
$agent1 = $dbh->prepare($sql) || die $DBI::errstr;
$Agent1->execute(291) || die $DBI::errstr ;
( $phone_no,$mail )= $Agent1->fetchrow_array or die "no results :(";
May I recommend you put RaiseError into your connection string? Less explicit dying.
