<?php include("enterPortal.php");?>
Basically what happens is, your displaying your form, but before hand, your asking if it has a username and password have been passed to the page, which of course they haven't (but they will when you submit the form?). Its not an error or a warning, but a notice so you can ignore it, its simply saying that it doesn't exist, but thats ok. You can supress it using error_reporting(E_ALL ^ E_NOTICE) (I think) or simply place an @ in front of it.
Having a quick look at EnterPortal, as it stands, if the user opens index.php, it'll spit out an error (cos you haven't entered a username yet), so I would reorganise EnterPortal.php to be something like.
PHP Code:
if($muser != "") { //User has entered something so its time to check
$sd = mysql_select_db("ifl-sales", $conn) or die ("Could Not Select DB");
$tableinsert = "select * from portalGuard where username = $muser and password = $mpass";
$sd = mysql_query($tableinsert, $conn);
if($user=$sd['username']) {
echo "Access denied!";
} else {
//Connected.
}
}
And another thing, at the moment its technically possible to use SQL Injection to completely mess up your db when you use a query like "select * from portalGuard where username = $muser and password = $mpass" that. You need to escape all inputs to make sure they don't do anything tricky (check out php.net for more info on it)
Cheers.

Re: undifined index.. :(
And in addition, your HTML form is wrong. Remove the onSubmit attribute and add an action attribute that contains the path to where the submit data should be sent, presumably enterPortal.php.
