the error message ends:

(#f Unbound variable: ~S (Incipit::params) #f)
Denemo - WARNING : 
                   The tag is
                   
unbound-variable

Which is telling you that Incipit::params in an unbound-variable. This
variable would be created if you invoked this script via a command
called Incipt - that is each command in the menu creates a variable
named xxxx::params when it is invoked (setting it to #f if its invoked
from a menu).
