Ditto Summary not working?

[risingisland]

I am using a basic Ditto call in home page with:

[[Ditto? &parents=`2` &display=`3` &tpl=`Intro-Blog` &extenders=`summary,dateFilter` &truncLen=`200` &truncOffset=`5` ]]

and a template with:

<h5>[+title+]</h5>
<p>[+summary:notags+]</p>

Am I missing something, why does this not work?

As a side note, there is no text in "introtext", I am trying to pull the first two sentences from "content".
Even with text in "introtext", it is still pulling full text from content.

I think I have figured it out. It looks like it might have been a cacheing issue.
I changed:
[[Ditto? &truncLen=`200` &truncOffset=`5` ]]
to
[!Ditto? &truncLen=`200` &truncOffset=`5` !]
And I think all is working as intended.
Will test a bit more before closing.
