I am trying to add TinyMCE to page but I am getting these errors:

Error: tinyMCE is not defined Source File: https://my.secure.site/tinymce/jscripts/tiny_mce/langs/en.js Line: 1 Error: tinymce is not defined Source File: https://my.secure.site/tinymce/jscripts/tiny_mce/themes/advanced/editor_template.js Line: 1 Error: tinymce is not defined Source File: https://my.secure.site/tinymce/jscripts/tiny_mce/plugins/pagebreak/editor_plugin.js Line: 1 Error: tinymce is not defined Source File: https://my.secure.site/tinymce/jscripts/tiny_mce/plugins/style/editor_plugin.js Line: 1 Error: tinymce is not defined Source File: https://my.secure.site/tinymce/jscripts/tiny_mce/plugins/advimage/editor_plugin.js Line: 1 Error: tinymce is not defined Source File: https://my.secure.site/tinymce/jscripts/tiny_mce/plugins/advlink/editor_plugin.js Line: 1 Error: tinymce is not defined Source File: https://my.secure.site/tinymce/jscripts/tiny_mce/plugins/iespell/editor_plugin.js Line: 1 Error: tinymce is not defined Source File: https://my.secure.site/tinymce/jscripts/tiny_mce/plugins/preview/editor_plugin.js Line: 1 Error: tinymce is not defined Source File: https://my.secure.site/tinymce/jscripts/tiny_mce/plugins/media/editor_plugin.js Line: 1 Error: tinymce is not defined Source File: https://my.secure.site/tinymce/jscripts/tiny_mce/plugins/paste/editor_plugin.js Line: 1

Here is the code I have in header:

<script type="text/javascript" src="https://my.secure.site/jquery/jquery-1.3.2.min.js"></script> 
<script type="text/javascript" src="https://my.secure.site/tinymce/jscripts/tiny_mce/tiny_mce.js"></script>
<script type="text/javascript">
$(document).ready(function() {
    tinyMCE.init({
        mode: "textareas",
        script_url: "https://my.secure.site/tinymce/jscripts/tiny_mce/tiny_mce.js",
        theme: "advanced",
        plugins: "pagebreak,style,advimage,advlink,iespell,preview,media,paste",
        theme_advanced_buttons1: "help,newdocument,|,bold,italic,underline,strikethrough,|,link,unlink,anchor,image",
        theme_advanced_buttons2: "fontsizeselect,hr,removeformat,charmap,visualaid,sub,sup",
        theme_advanced_buttons3: "cut,copy,paste,|,undo,redo,|,cleanup,code,preview",
        theme_advanced_toolbar_location: "top",
        theme_advanced_toolbar_align: "left",
        theme_advanced_statusbar_location: "bottom",
        theme_advanced_resizing: false,
        editor_selector: "tinymce",
        width: "398px",
        force_p_newlines: false,
        force_br_newlines: true
    });
});
</script>

And this is my textarea that I'm expecting TinyMCE to use:

<textarea id="post1msg" class="tinymce" rows="4" cols="40"><?=$r->post->message?></textarea>

Please does anyone have any idea why it's not working?
