Embedding Gist into Blogger not working

I have the following gist...

https://gist.github.com/4445255

I try adding it to my Blogger entry (per here) into my post by adding this to the very end...

<script src="https://raw.github.com/moski/gist-Blogger/master/public/gistLoader.js" type="text/javascript"></script>

finally in position I add

<div class="gistLoad" data-id="4445255" id="gist-GistID">Loading ....</div>

But it just shows loading...

Solution

I hadn't yet converted my project over to a Dynamic View. So I went to Template>Dynamic View.

There is a little issue, saving formatting only seems to work in IE for dynamic views...
