[Zope] PoPy Database Connection

Hello All. I finally got my Popy Product working, but now I'm trying to create a database connection, following the instrucions I fill the database connection string following the instruction on screen. user=username host=hostname dbname=dbname port=port password=password I just need the username dbname as the default value shows in the text area shows. Now the problem is that when I try to connect I get the next error Invalid connection string: user=gerardo1 dbname=test Powered by Zope I try every combination with no success, what do you all think the problem could be? thanks in advance Gerardo Amaya
