When using forms with a lot of text fields, PHP forgets some of the variables.

Excerpt from the input form:
     printf ("<tr>");
     while (ora_fetch($curs)) {
        $resultrows = $resultrows + 1;
        $tprogram = ora_getcolumn($curs,2);
        $thpage = ora_getcolumn($curs,3);
        printf ("<tr>");
?>
        <td>
        <input type="hidden" name="tmarker<?echo $i;?>" value="C">
        <input type="checkbox" name="tdelete<?echo $resultrows;?>" value="del">
        </td>
        <td>
        <input size=25 name="tprogram<?echo $resultrows;?>" value="<?echo $tprogram;?>">
        </td>
        <td>
        <input size=25 name="thpage<?echo $resultrows;?>" value="<?echo $thpage;?>">
        </td>
<?
        printf ("</tr>");
     }

When filled out with:
tprogramX      thpageX
sdfsdf aa     - ddf
b                - b
c                - c
d                - xpage 

using:
  while (list($var, $value) = each($HTTP_GET_VARS)) {
                                  echo "$var = $value<br>\n";
                              }
shows that the last textfield ("xpage") is not stored in a PHP variable (it doesn't matter if I'm using PUT og POST in the form).
