ModX: Display multiple pages on one page -How to implement
===

I understand I am meant to use Ditto to do this but am unsure where to go from there.

Currently, I have a Template with all my TVs on it along with several pages using the template that are stored under a parent. The Ditto code I am using is:

    [!Ditto? &parents=`173`&orderBy=`createdon ASC` &tpl=`showtemp` &display=`100` &total=`100`!]

However, when I view the page I get the error:

    &tpl either does not contain any placeholders or is an invalid chunk name, code block, or filename. Please check it.

My chucnk ('showtemp') looks like:

    <div class="showmedia">
    [*showmedia*]
    </div>
    <div class="showright">
    <h2>[*showname*]</h2>
    <h2>[*showtime*]</h2>
    </div>

As far as the set up goes I am not sure if I am going about it right. 

Do I make a Chunk as if it were a normal template with TVs, then replicate it as a proper template, create the resources and go from there?

If someone could give me a step by step on how to do this correctly I would be very grateful! Thanks
