    tr/td breaks the form. Try using div's instead.

    Replace checkform javascript function:
    PHP Code: 
    function checkform ( form )
    {
      if (    form.marks.value == "") {
            alert( "Please enter marks." );
            form.marks.focus();
        return     false ;
      } 
          // ** END **
          return true ;
    } 
    With:
    PHP Code: 
    function checkform ( form )
    {
      if (    form.elements["marks[]"].value == "") {
            alert( "Please enter marks." );
            form.elements["marks[]"].focus();
        return     false ;
      } 
          // ** END **
          return true ;
    } 
    This should work to validate the marks first.
