Problem writing Ubiquity javascript command

I had a problem writing a javascript command for Ubiquity. The command is "boinc" and it is supposed to bring up an image of my BOINC stats in the preview before the command is executed. However, once I subscribe to my own command, Ubiquity appears to have forgotten all commands, period. Nothing but a complete uninstall and reinstall helps.

My command can be found on this page:

What am I doing wrong?
