PHP Integrating PHP with Databases Limiting Records in SQL Pagination Function

Function named pagination, accepts four arguments

I keep getting an error with line 29. I've been scratching my head for awhile but can't figure it out. I tried with and without the curly brackets. Both ways give me errors.

index.php 
<?php
include "pagination.php";

/* add function here */
function pagination($total_pages, $current_page, $section, $search) {
/* setting pagination variable */
$pagination = "<div class=\"pagination\">";
$pagination .= "Pages: ";  
for ($i = 1;$i <= $total_pages;$i++) {
    if ($i == $current_page) {
        $pagination .= " <span>$i</span>";
    } else {
        $pagination .= " <a href='catalog.php?";
        if (!empty($search)) {
            $pagination .= "s=".urlencode(htmlspecialchars($search)) . '&' ;
        } else if (!empty($section)) {
            $pagination .= "cat=".$section . '&';
        }
        $pagination .= "pg=$i'>$i</a>";
    }
}
$pagination .= "</div>";

return $pagination;

}

/* displaying the pagination */
echo $pagination($total_pages, $current_page, $section, $search){};

I figured it out. On line 29 I did not need the '$' in front of pagination.
