My page is not loading right

I have been on this for hours on end. When I get one thing working something else doesn't work. Well now my page is not loading to the one it is suppose to. It is loading to the content page and not the form page.I have the home page in for the users to enter in there username and passowrd and if they dont have one then they can register on the form. I put all the forms on there. I don't know what I am doing wrong. Like I said I been working on this for hours. Can someone help me thanks. Its not loading to the form it skips right over it to the content page. So if you click on register to the form you wont see it. It will go to the content page. Here are my codes This one is form page..

<?php

function FormDisplay($strMessage="**All fields are required!"){
echo "<p><strong>".$strMessage."</strong></p>\n";

This is the signin form:

         <?php
include("config.php");
if ($_POST['username']==""|| $_POST['password']==""){
    header("Location:member-home.php?mode=1");
}
else{

    }
 }
 $SQL="Select username from tblusers where username='".$_POST['username']."' AND password=PASSWORD('".$_POST['password']."')";
 $resultSet=mysql_query($SQL);
 if (mysql_num_rows($resultSet)>0){
    $username=mysql_result($resultSet,0,"username");
    header("Location:member-content.php?name=".$username);
 }
 else{
    header("Location:member-home.php?mode=2");
    }
 }
 ?>

You have a misplaced semicolon in your member-form.php:

if ($_POST['username']==""||$_POST['password1']==""||$_POST['password2']==""||$_POST['firstname']==""||$_POST['lastname']==""||$_POST['address']==""||$_POST['email']==""||$_POST['city']==""||$_POST['state']==""||$_POST['zip']==""||$_POST['phone']=="");

so you need to replace it with opening curly bracket.
