Sorry the error is that the server is rejecting it, saying it's an invalid input.

This code works 
  $request = POST "http://www.server.com", Content => [ $formname1 => 
+'formvalue1', $formname2 => 'formvalue2' ];

While this one causes the server to redirect to an error page. However, I have to do it this way, because I need to build the form parameters using a for loop. 
  $hiddenhash{$formname1} = 'formvalue1';
  $hiddenhash{$formname2} = 'formvalue2';
  $request = POST "http://www.server.com", Content => [ %hiddenhash ];
