How can I use sTinyMceEditorJS

Hi,

I have created a new page under the Admin pannel and want to use the sTinyMceEditorJS what shell I do????

I added the line:

$_page['extra_js'] = $oTemplConfig -> sTinyMceEditorJS;

So I have this line and in the textarea :

<td align="left">
<textarea class="classfiedsTextArea" name="event_desc" id="event_desc_id" cols="80" rows="40">$eventDesc</textarea>
</td>

What shell I do next since it's not coming to my page...

I'm trying to find where is the function and in which php file

Thank

make the id and class to blogText
