Have you any html, white space etc before the session is started? Since you go straight into the form html after the session checking I assume you probably have your html tags before the session is code. If this is the case you must move all this to after the session code as no html etc can occur before the session code.

Well it resolves the first 2 errors....i post my complete code

In the it says a e:/php/sessiondata....etc....but thats not the root where the php is installed.

Remaining errors are:
