Hey gurus. I just installed WAMP on my PC and I tried accessing my designs on localhost but I get notices like: Undefined index: user in C:\wamp\www\DemoADResources\index.php on line 297 and my line 297 looks like this: <name="user" type="text" value="<?=$_POST['user'];?>" size="20"> these notices stops the script from executing. What do I do to go around these errors?
Getting these errors with WAMP server

Notices do not stop your script from executing. They point out problems in your code.
You're trying to use variables that aren't set yet. In this case, array indices, most likely from $_POST.

I was just trying to echo the user input should error(s) occur during submission. How do I go about it?

The manuals I learned with doesn't say how to go around this, didn't mention it at all

You need to check if the value isset() first.

You mean something like: if( isset( $_POST['user'] ) ) { $user = $_POST['user']; }

Well that would work if you either give $user a default value as well or check if IT is set before using it.
