Re: More data on Problem with nested tables

    Hello Werner,

    Your HTML seems wrong to me, just copy pasted in DW and shows a lot 
of tags placed incorrectly.
I found 2 <tbody> and </tbody> tags in wrong place, i think these should 
be <table> tags .
    Also make sure you close your iterative models in the same level 
where you opened them (i.e. if you opened
in a TR than end it in a same level TR element)

I hope it helps a little bit,
Andras.
