PHP Conditional Issue

I have a small problem. And I am not sure why am I getting this problem. See what I did was I limited a page to “Public Member” and I want this page to be access Library members too because library members would have access to all pages. So what I did was I added a simple condition like this:

if ( $user_role == "library-Member"  && $pageLevel == "public-member" ) {
    $displayPost = "true";
}

And in my post I added this condition

if ( $displayPost == "true" ) {
   .. execute html stuff ..
}
else {
   wp_redirect( 'http://sample.org/restricted-area' );
   exit;
} 

But somehow the condition is not working. I have also checking var_dump($displayPost) the output is true

Can someone help me please? Thanks.

CODE:

<?php

$pageLevel = get_post_meta( $post->ID, 'user_type', true );

if ( $user_role == "library-Member"  && $pageLevel == "public-member" ) {
    $displayPost = "true";
}

if ( $displayPost == "true" ) {
