Waaahhhh... code highlighting should be on highest priority :-)
Again the replacement:
IIF(InStr(IconHtml(DataBinder.Eval(Container, "DataItem.Icon16")),"[div"), IconHtml(DataBinder.Eval(Container, "DataItem.Icon16")), "[img src=" & Chr(34) & DotNetNuke.Common.ResolveUrl("~/" & DataBinder.Eval(Container, "DataItem.Icon16")) & Chr(34) & "]" )
...all rectangular brackets to be replaced with their corresponding > and < :-)
