I'm stuck trying to get work this : This is an example page1.php ======================================= <form action="/page2.php?form=yes" method="post"> $sql_pro ="SELECT Sid FROM table"; $res_pro = @mysql_query( $sql_pro); while ($campo_pro = @mysql_fetch_array($res_pro)) {

      $sid_pro = $campo_pro["Sid"];  //  *sid_pro = 4*
      $sid_pro = 'p'.$sid_pro;     // I'm trying to use de value of $sid_pro as a VAR name *$sid_pro = p4*
      print "<td > *<input name='$sid_pro' type= 'radio'  value='SOLVE_ME'/>* </td>";  // *name=p4 *
       BLA BLA BLA

}

      SUBMIT FORM

======================================= page2.php ======================================= $sqlname = "SELECT Sid FROM Table"; $res = mysql_query ($sqlname) ; while ($campo_pro = mysql_fetch_array($res)) {

       $name1 = $campo_pro["Sid"];  // *$name1 = 4*
       $radio = '$'.'p'.$name1 ; // *$radio = $p4
