Net List Name vs Port Name -- Newbie Protel DXP Question

I have a level shifter IC and 2 headers on a board..

So in the schematic I have a header with different port names for each pins. On the IC, Id like to connect to these header pins without drawing wires all over the place, so I created a port name to a wire going to the IC that matches the port pin that I wish to connect of the header.

This doesnt seem to work, when I compile I get "multiple input" errors.

How can I do this? All the signals will come from the header, go to the IC, and from the IC to another header. What am I doing wrong??
