					if($username_control != 0){ echo $_POST['username'];}

					elseif(username2_control !=0){ echo $_POST['username'];} 

					elseif(username3_control !=0){ echo $_POST['username'];}

					else{ echo ''; }  ?>"> 

					<?php echo $empty_username; ?> &nbsp &nbsp

					<input class="button" type="submit" name="submit" value="Get password">

					<?php echo $_POST['username']; ?>

					<input type="hidden" name="set" value="set">

				</form>

<?php 
{ 

if ($_POST['submit'] == "set") { 

if ($_POST['username']) 
{ 
        validuser(); 
} 

}else{ 
        info(); 
} 
?>

i think there is a problem with the last statement... yours reads

{  

if ($_POST['submit'] == "set") {  

if ($_POST['username'])  
{  

        validuser();  

}  

}else{  

        info();  

} 

I think it should be

if ($_POST['submit'] == "set") {  

if ($_POST['username'])  

{  

        validuser();  

}  

else
{  

        info();  

} 

} //close "set" if

try that n let me know 🙂

        below to recive your password.<br> 
        Then press get password button to recive your<br> 
        password.<br>"; 

?> 

<br> 
                        <form action="<?=$PHP_SELF?>" method="post" name="hej"> 
                        <b>Your Username Here:<br><br></b> 
                        <input type="text" name="username" size="15" class="inputSidebar" val="<?php 

                    if($username_control != 0){ echo $_POST['username'];} 

                    elseif(username2_control !=0){ echo $_POST['username'];}  

                    elseif(username3_control !=0){ echo $_POST['username'];} 

                    else{ echo ''; }  ?>"> 

                    <?php echo $empty_username; ?> &nbsp &nbsp 

                    <input class="button" type="submit" name="submit" value="Get password">
