Oops! I had one too many PreExecute block marks in there... This might be
more like it:
<!IoRangePreExecute><% counter = 1 %><!/IoRangePreExecute>
{"Image": [<!IoRangeList><!IoRangeRedDotMode><!--<%lst_plSW%>--><
!/IoRangeRedDotMode><!IoRangePreExecute><% if "<%std_url%>" <> "" then %>
<% if counter > 1 then %>,<% end if %>
{ "YouTube-Titel": "<%hdl_ueberschrift%>",
"Hersteller": "<%!!
Context:Pages.GetPage(Guid:<%inf_pageGuid%>).MainLink.OwnerPage.Headline
!!%>",
"Kategorie": "<%ol_videoTyp%>",
"URL": "<%std_url%>"
}
<% counter = counter + 1 %>
<% end if %><!/IoRangePreExecute><!/IoRangeList>
]}
Cheers,
Mark
