options has not been redefined anywhere. The problem appears to be in 
the way to call a particular python script

this is a bit long, but interesting nevertheless -:)

the variable in question is 'compname' which is either 
request['compname'] or options['compname'] depending on how the ZPT 
is called (from web it goes to 'request' and from script in goes to 
'options')

This is the script:

callheadtree.py
parameter list: compname

theads=context.getheadleafs()
heads=[]
for k in theads:
   heads.append(k['id'])
htree=context.getheadtree(compname=compname,id=1,name='chart',ret=[],heads=heads)
headtree=[]
for k in htree:
    headtree.append({'name':k})
return headtree

when tested using the test tab it works
when the originating ZPT is called from the web using '?' notation it 
works
when called from the following script:

onetest.py
names=callheadtree(compname='testcompany')
return names

it gives a Keyerror 'compname'

when the originating ZPT is called from a script:

it gives a Keyerror 'compname'
