i understand, that you call a DTMLMethod, which contains these calls

from the top of my head
myResult_if_any = myDTMLMethod(self, REQUEST=REQUEST)
or
myResult_if_any = myDTMLMethod(self)

This effects a "binding" of the REQUEST object (right hand side)
to a parameter named REQUEST (in the second case default = {}
