When attempting to insert data into an access database I have discovered that none of the fields can be left blank. I have worked arounded by providing values that are displayed in the form for the user to typeover. Why do I need to provide values and is there a better way to handle this? This is tweaked code. I'm a novice perl writer.

#!/perl/5.005/bin/MSWin32-x86-object/

# Use the module
use CGI; 

# Use the ODBC module
use Win32::ODBC;

# Create a connection to the form
$q = new CGI;

# Define the DSN
$dsn = "helpdeskevaldb";

# Create a connection to the DSN
$db = new Win32::ODBC($dsn);

# Output the header and the start of the HTML
print $q -> header();
print $q -> start_html(-title=>'Evaluation Form');


# Query the form fields
$ID = $q -> param('ID');
$STFN = $q -> param('STFN');
$STLN = $q -> param('STLN');
$SRTLookup = $q -> param('SRTLookup');
$ToPRLookup = $q -> param('ToPRLookup');
$PSKLookup = $q -> param('PSKLookup');
$OSRLookup = $q -> param('OSRLookup');
$AC = $q -> param('AC');
$FN = $q -> param('FN');
$LN = $q -> param('LN');
$Dept = $q -> param('Dept');
$Phone = $q -> param('Phone');
   # Save the form field data to the database
   my $rc = $db -> Sql("INSERT INTO EVAL (ID, STFN, STLN, SRTLookup, T
+oPRLookup, PSKLookup, OSRLookup, AC, FN, LN, Dept, Phone) 
   VALUES ('$ID','$STFN','$STLN','$SRTLookup','$ToPRLookup','$PSKLooku
+p','$OSRLookup','$AC','$FN','$LN','$Dept','$Phone')");
   # Return a success message
   
   print $q -> h1("Thank You for participating in our survey!");
   print $q -> p("Data saved to database.");

# Close the connection to the DSN
  $db -> Close();
  
# End the HTML and exit the script
print $q -> end_html();

exit(0);
