The relevant sections of the .do file are:

First of all do not contact members of the statalist
privately with such questions, that is where the 
statalist is for:

<http://www.stata.com/support/faqs/res/statalist.html#private>

Second, choose your subject line a bit more carefully.
Normally I would automatically move emails from unknown
persons with such a subject line directly in the spam 
folder. It is just that Palmer happens to be the name of
the mayor of my town that I got curious enough to open it.

To answer your question: Change

return scalar `prod2' = ...

to 

return scalar prod2 = ...

and

bootstrap p=r(`prod2'), nodrop: twopart

to

bootstrap p=r(prod2), nodrop: twopart

Hope this helps,
Maarten
