[Zope] newbie, setting member properties in python

I am trying to create a simple script that loops through the member properties and sets certain boolean ones to a certain value (which I have acquired). I realize I am probably making a simple mistake but the following snippet of code doesn't seem to set the member I am interested in. Any help would be appreciated. p_index =-1 for p in memberProperties: p_index = p_index+1 curr_value = cb_array[p_index] if p[0] == i #(checking for properties beginning with an i but could be any check) member.setProperties(p=curr_value); thanks in advance for any help, Dan
