TypeError: $ (...). JqGrid is not a function

I want to create a jqgrid table .. but I found an error and was confused to fix it.

This is my screenshot

This is my script:

index.php

<script src="js/jqgrid/js/jquery-1.5.2.min.js" type="text/javascript"></script> 
    <link rel="stylesheet" type="text/css" media="screen" href="js/jquery-ui/css/custom-theme/jquery-ui-1.8.16.custom.css" /> 
    <link rel="stylesheet" type="text/css" media="screen" href="js/jqgrid/css/ui.jqgrid.css" /> 
    <script src="js/jqgrid/js/i18n/grid.locale-en.js" type="text/javascript"></script> 
    <script src="js/jqgrid/js/jquery.jqGrid.min.js" type="text/javascript"></script> 
    <script src="js/jquery-ui/js/jquery-ui-1.8.16.custom.min.js" type="text/javascript"></script> 


    <style type="text/css"> 
        div.ui-datepicker
        {   font-size:10px; }

        div.ui-dialog
            {   font-size:11px; }

        div.ui-tabs
            {   font-size:11px; }

        .ui-jqgrid tr.jqgrow td {
            white-space: normal !important;
        }

        .center { width: 640px; margin-left: auto; margin-right: auto; }

    </style> 

    <style type="text/css">.ui-jqgrid .ui-jqgrid-bdiv { overflow-y: scroll }</style>
