Bob its in the picture attached above. It just has three chunks basically. For now can we not worry about the front page, which seems ok even if it can't be found. We can find that later for sure.
Ok I think I see what is going on, at least a little bit. The tools are in those chunks.
In this case what you are getting on those pages is default text, as the parent resource is empty. Here is the code where this happens:
[[+latest-news:empty=`this default content will show if empty'
The tool is getResources, so let's talk about how it gets the info. Basically you should look for the parent resource (4 for the first one, 21 for the second two which needs fixing, they should each be different).
Try this: Make a new resource and place it in resource 4 (ID number of resource). This new page will be your content about your new (dummy) event. Publish it too.
That should make it visible in the tool and it should output on the page, no more latin. For each new event, write it up in a new resource, drag and drop into the parent resource (which can be a container and/or have its own content), and publish.
Because you have the same parent resource for the second two tools (getResource calls), they will be identical, so you will want to make a new resource and change the 21 to that resource number. Then you will have three folders and the tools will always dynamically go get...hmmm some content let's see...I suppose it will be the latest item (its limited to one) but not positive now.
So, give it a try and let us know!
PS I still don't know why the front page is getting different contents...
