Hi Nick,
it's a bit difficult to debug your script when you didn't use the syntax highlighting provided by this forum. Could you please edit your post insert the CODE tags?

Could I see the script at work somewhere? In general, the problem is either in HTML (answers are overwriting one another) or in processing the response. It would be easier for me to check the first area if I could see the HTML directly.

Also, your sample data contains only one item so it cannot show the behaviour you've described, right? Could you add more and use some real life data? The problem could be there too.
