[Zope] dtml-in syntax

[Montagne, Michael]

zAllProjRoles is a zsqlmethod that returns as one of it's fields Projteamid.
I can get a value if I use <dtml-var Projteamid> within the loop.
ProjTeamPhones takes an argument called Projteamid.  It should return all
the phone numbers for this id number.  But this code gives me 
a 'Bad Request Error' on 'Projteamid'.  How can I pass the correct value?
