Hi, everybody,
I can´t reproduce the solution I suggestet either and I do not know anymore what made me posting the stuff.
So, you better do not delete anything! Sorry for that...
Meanwhile I finished the calendar I was working on and it works fine. I get the Event results in the place I want them (the middle column of my page) by placing the listDetailsContainer in the proper <div>:
<div id="main">
<div class="leftcol">
<h1>[*description*]</h1>
<div id="ee_listDetailsContainer">
[+listDetailsPlaceholder+]
[+missingEventsMessagePlaceholder+]
</div>
</div>
<div class="rightcol">
<div id="ee_miniCalendarContainer">
[+miniCalPlaceholder+]
</div>
[[EasyEvents_ListMini? &nodes=`157`]]
</div>
</div>
You can see the result here on the temporary project site:
http://www.marcus-buchwald.de/kunden/bad-karlshafen/index.php?id=154. If this link doesn´t work anymore, the project is finished most likely; try this link then:
http://www.bad-karlshafen.de (Click "Kur & Tourismus" and then "Veranstaltungen")

. I need to go directly to the events page when I click on the event date on the calendar, instead of it displaying at the bottom.
