How can I put an RSS Feed on a page.

I searched far every where, and used every thing available- I must have made 8 snippets- none work (parse error). PieX’s parse error was around line 1089- whew one long snippet.
I am running a SMF forum outside modX, as the instructions to run it inside were a bit complicated. Now you know my skill level.
I would like to put an rss feed from the Forum onto a page in modX, the last thing I tried was the ’BASIC Rss Feed using Ditto.
I create a page called RSS Feed, id= 52, using the "Page settings" as directed. I use the ditto call as directed [[Ditto? &startID= ’52’ ect.
In the header of the template, I comment out the existing rss feed link rel using //’s and insert the one from the directions.
(I never delete anything that worked, for fear I will need it one day)
In this link rel, I use the href where my forum feed is located:
http://www.mysitenamehere.com/forum/index.php?action=.xml;type=rss2;sa=recent;limit=2. (I got this from a SMF forum)
I do this because it says ’the url of the page with the ditto rss call. This is the only place I can find to point to the url of my forum.
If this is the problem, can someone tell me where the tutorial doing something like this is? Or better yet how to point to the forum.

I was almost there with [snippet]xslt until I had to search the web to find out how to build a xsl file. (too much info)
&xslFile=`/assets/templates/mytemplate/testStyle.xsl` (not included in the download).
Any help you can give me would be appreciated.

You need to generate the feed from the forum, then use a snippet like FeedX to "consume" and display the feed on MODx.

Ditto generates feeds, it doesn’t "consume" and display them.
