Hi, I have not taken the time to look into your code but to make a region
editable within a template is fairly straight forward. I manually input the
codes in the code view for better accuracy.

<div >

<!-- TemplateBeginEditable name="MainText" --> This is just some text
<!-- TemplateEndEditable -->

</div>

You have to insert the middle code within your template page. The code has to
be inside the div tags you want to make editable. Be sure to name it uniquely
from other editable regions. Hope this works.
