Note Submitter: christopher dot jamieson at bell dot ca ---- Can someone help me please? I get the following error: Parse error: syntax error, unexpected T_ENCAPSED_AND_WHITESPACE, expecting T_STRING or T_VARIABLE or T_NUM_STRING in c:\wamp\www\Form\form_main2.php on line 79 when i run the following code: $action="$_SERVER['PHP_SELF']" echo "<form action=$action method='post'>"; I am new to PHP so it is most likely an obvious mistake but never the less I cannot figure it out. Thanks in advance!
