Problems Generating allegro netlist from orcad schematic

I have been having problems generating a netlist for Allegro pcb editor from an OrCad schematic. I have created package symbols and padstacks for all of the parts I am using. In the Orcad schematic I have specified the allegro part symbols (.psm files) for the "PCB footprint" property. When I try to generate the netlist it fails because #1 Error [ALG0012] Property "PCB Footprint" missing from instance C12: SCHEMATIC1, Buttons_Switches (8.30, 8.80). There is a similar message corresponding to each schematic symbol. If anyone has experience creating an allegro netlist from an orcad schematic any help would be appreciated. On another note I am able to manually place the packages I have created... I would be willing to skip the netlist step and manually enter the net information, but do not know how to assign a reference designator to a manually placed package symbol, and manually enter logical information. I do know that i need to set the logic_edit_enable environment variable... but using environment editor doesn't seem to have an effect on the pcb editor functionality...even though the logic_edit_enable variable is checked and after the saving the settings and reopening them it remains checked. Sorry if these are stupid questions ... I am in college working the final stages of my senior project and have almost no PCB layout experience and am trying to pick up OrCad/Allegro very quickly. If can be of any help at all it would be greatly appreciated
