Default ODBC in Perl to display SQL data?

Hi, I am stumped - new Perl user. . .

I am using the standard HTML form page for people to submit a name to search one name field called panelist1 in our SQL db (would like it to be multiple fields since there are 9 name fields there). If the search comes up with a name close or matching to the user's search terms, I want to display back on the web that panelist's name, the Title (another field) and the broadcastDate (another field). The problem is when I try to run this, I keep getting that pesky "CGI error: The specified CGI application misbehaved by not returning a complete set of HTTP headers."

I tried: 1.) Running this at the MS-DOS command prompt at the server and got "use of unitialized value in string eq at line 12" - referring to this line:
       if ($query->request_method() eq "POST")
Not sure what it is looking for?
2.) Inserting different headers, like the standard
    print "Content-type: text/html\n\n";
but this didn't change the CGI error.

So here is the coding for the Perl script, called search.pl :


  use CGI;
  use DBI;

  $query = CGI::new();
  print $query->header();
  print $query->start_html(
     -title=>'Search Broadcasts by Presenter',

 if ($query->request_method() eq "POST")

 print $query->end_html();

 sub ProcessForm # * Begin ProcessForm SubRoutine *
    $searchname = $query->param("panelist1");
    # $sql = "SELECT * FROM Teleconferences WHERE panelist1 ='$searchname';";
    # or
    $sql = "SELECT * FROM Teleconferences WHERE panelist1 LIKE \'%$searchname%\';";
    $dbh = DBI->connect('dbi:odbc:OURweb', '', '', ,
           { RaiseError => 1 });

    $cursor = $dbh->prepare($sql);

    print "<H2>Search Results</H2>";
    print "You searched for: <B>$searchname</B><BR>";

    while (@row = $cursor->fetchrow_array)
       push @panelist1, $row[0];
       push @Title, $row[1];
       push @broadcastDate, $row[2];
    if (scalar(@panelist1))
        print "<TABLE BORDER=1><BR>";
        print "<TR><TH>Panelist<TH>Title<TH>Broadcast Date<BR>";

             for ($i=0; $i<scalar(@panelist1); $i++)
                print "<tr><td align=right>$panelist1[$i]";
                print "<td align=left>$Title[$i]";
                print "<td align=right>$broadcastDate[$i]";
        print "</TABLE>";
        print "<A HREF='search.pl'>Return to the search page</A><br>";
    print "No records found for \"$searchname\".<p>";
    print '<a href="search.pl">Return to the search page</a>';


 } # *** End ProcessForm ***

 sub PrintForm # *** Begin PrintForm SubRoutine ***
    print <<ENDOFTEXT;

    <FORM METHOD="POST" ACTION="search.pl">
    <H2> Search Broadcasts by Presenter</H2>
    Enter the name of the presenter you wish to search for: <BR>
    <INPUT NAME="searchname">

 } # *** END PrintForm ***

Any advice, clues or hints would be appreciated! Thanks.
