This’ll work:
[!Ditto?&startID=`0`&tpl=`CHUNKNAME`&filter=`id,67`&summarize=`1`&displayArchive=`0`&trunkText=`more...`&descendentDepth=`99`!]
create a new chunk with the following Code, As long as it’s name matches the &tpl=`CHUNKNAME` in your ditto snippet call you’re good to go.
{{CHUNK}}
<div class="homeSummery">
<h2><a href="[~[+id+]~]">[+longtitle+]</a></h2>
<p> [+summary+]</p>
</div>
It seems kinda odd to want a single id on the page, you might as well add the content to the home page it’s self.
I would suggest a convention. Set up a container and rotate content on the home page based on the most recently published document in that directory.
[!Ditto?&startID=`contanerID`&tpl=`CHUNKNAME`&sortBy=`pub_date`&sortDir=`DESC`&summarize=`1`&displayArchive=`0`&trunkText=`more...'!]
This will output the summery for the most recent page added under your "containerID"(numeric). Giving your homepage the much sought after Google appeal...
hope this helped.
