Hello, I am working on a redirection script that will allow the an administrator to enter a specific name with url link into a database. So, it would saved like this: 
$name\|$url

The problem that I am running into is on the users side. I want to use a <input type=text value=name>,not a drop-down menu. Here's the problem, when a $name is entered in the box, that is not in the database, I get a "file not found" . I'm trying to figure out how to set up the script so that if the $name is invalid they get a preset error message.

Here's the script I'm working with: 
#!/usr/bin/perl

$datafile = "/home/sites/www.yourname.com/users/web/mysites.txt";


############ THE ACTUAL PROGRAM ############
&parse;
&incomplete unless $FORM{'name'};

$name = "$FORM{'name'}";


&findurl;
&doit;

############ SUBROUTINES ############

sub doit
{
 print ("Location: $url\n");  
 print ("Content-type: text/html\n\n");
}

 
############ FIND URL ############

 sub findurl
{ 
          
        
    open (INFO, "$datafile");
    @information = <INFO>;
    
    foreach $information (@information) 
    {
    ($title, $location) = split(/\|/ , $information);
    { 

        if ($title eq $name)
        {
        $url = $location;
        }
        
    }
    }
    
        
   close (INFO); 
 
}

############ PARSE ############

sub parse
{
 read(STDIN, $input, $ENV{'CONTENT_LENGTH'});

    $input = $ENV{'QUERY_STRING'} if $ENV{'QUERY_STRING'};

        @pairs = split(/&/, $input);

        foreach $pair (@pairs) {
        ($name, $value) = split(/=/, $pair);

        $value =~ tr/+/ /;
        $value =~ s/%([a-fA-F0-9][a-fA-F0-9])/pack("C", hex($1))/eg;

    $FORM{$name} = $value;

 }
}


sub incomplete
{
print "Content-type: text/html\n\n ";
    
    print <<"HTML";
<HTML><HEAD><TITLE>Incomplete</TITLE></HEAD>
<BODY bgcolor=white>
<H1>Form not complete</H1>
<p>
<hr noshade size=1>
<p>
Sorry, you forgot to enter something.
<a href=\"$ENV{'HTTP_REFERER'}\">You should go back and try again</a>.

</BODY>
</HTML>
HTML
exit;
