Question about buses

Hi all,

I'm new to ORCAD and I'm just starting to learn Capture. I've made a
few simple layouts and I'm starting to get a good feel for the
program. However, I've been unable to get a bus to work as of yet. It
seems like every time I try to make a bussed circuit, Capture gives me
an error about bus width when I go to check the design rules.

Is there anything more to putting a bus into a circuit then drawing
the bus, adding bus entries on either end of the wire, and then
connecting these to their various parts? What am I doing wrong?

Thanks,
-Nick
