Can't fix instapaper recipe

[nyy27wc]

The instapaper built-in recipe won't give me more than the last 40 articles. I believe the problem could be that instapaper only puts 40 articles on each page at their site and the next ones are on subsequent pages.

So I tried editing the built-in recipe. I made 2 changes: (1) I added more pages to the feeds area and (2) I increased the maximum articles up to 1000.

But then when I hit save, I get the following error: "Invalid recipe" "Failed to compile the recipe with syntax error: 'tuple' object is not callable"

Here is what the complete revised recipe looks like:

# Calibre recipe for Instapaper.com (Stable version)

How should I fix the recipe so I can get the subsequent pages and not get the error?
