You may test "if (!count($required))". However this will also NOT give you the results you're looking for - the test will fail if at least one key has been set... and forms don't transmit elements that have not been filled, so these keys are omitted from $_REQUEST completely. What do you really want to achieve? -- >O Ernest E. Vogelsinger (\) ICQ #13394035 ^ http://www.vogelsinger.at/
