vars from page to page

Hi NG. I have a little problem with a new install of php/apache/win2k which has to do with the setup I think. I have made a webpage on a local machine php/apache/win98 which runs perfectly. But when I transfer it to the new installation it seems that vars doesn't travel between pages. As an example, this should work but doesn't: page code example: ============== echo "click this <a href='$PHPSELF?action=say&msg=Hello_php_noob'>link</a>"; if (isset($action)) { echo "<br>". $msg ." so you did click the link huh ;o)"; } ============== page output before click: ------------ clik this link page output after click: -------------------- click this link Hello_php_noob so you did click the link huh ;o) This is what should have happened... But $action isn't set and nor is $msg, what can be wrong with the setup? Any help appreciated.... /Aidal
