Then you won't want to use my add-in. It has an arbitrary limit set
for about 1000 web  page retrievals, because it saves the source code
of each web page in case multiple data items are being retrieved from
the page. Unless I'm misinterpreting your statement. But if you're
really getting that much data, I would think there would be an easier
way to go about it?

Can you give an example URL? I couldn't tell what the valid values
might be for the parameters you were using in the web query.
