Hello,
I just found the problem with my code and the Invalid options node
error message! Sorry for bothering you, it works now.

The line <b>tested {$doi} ...</b> should not have been *inside* the
spawn function, because it was of course considered the third
parameter of this function which is an options element ...
cheers,
Jakob.
