problems with integration

[Han]

The only suspicion I have left is that there are some whitespaces that are not recognized by the emulator. In your screenshots, there are spaces at the start of each line whereas when I copy/paste the code I do not have spaces at the start of each line.

I've attached a zip file with the actual program. You can drag it into the connectivity kit (left pane, bottom section) and send from there, or copy it to your HP Prime folder for the emulator.
