Hi, I'm working on a ZClass for Trainings. The visitors of the site have to be able to fill in a form online to join a training. At top of the form there is first shown some information about the training. I want to show this info with the GET method of a hyperlink. Like this: <a href="/form/main?<dtml-var PATH_INFO>" methods="GET">Online sign-up</a> The following thing to do is split the PATH_INFO variable and join it with dots: <dtml-let splitpath="_.string.split(QUERY_STRING,'/')" training="_.string.join(splitpath[1:],'.')"> Then I want to get the attributes of the training with the dtml-with tag: <dtml-with "training"> <table cellpadding="3" cellspacing="0" border="0" width="100%"> <tr><td>Institute:</td><td><dtml-var institute></td></tr> <tr><td>Location:</td><td><dtml-var location></td></tr> <tr><td>Title training:</td><td><dtml-var title></td></tr> <tr><td>Start date:</td><td><dtml-var date_start></td></tr> <tr><td>Stop date:</td><td><dtml-var date_stop></td></tr> </table> </dtml-with> </dtml-let> Institute, location etc are attributes of the ZClass Training. The 'with' tag doesn't work; I get KeyErrors. Can somebody help me? Greetz Nico
