[Koha] MarcEdit / Koha Set-up

I've been struggling to set-up the Koha integration in MarcEdit. I searched the mailing list archive and found a useful thread on the need to designate a listen to port. I passed on the information to the person helping me out, but it still isn't working. This is his description of what he did. Are we on the right track?

...

I just uncommented that listen tag & set the port to 8080. I also uncommented the server/serverinfo sections (which the koha-conf.xml file said to do if you uncomment the listen tag). BUT, I'm not sure what it wants the "ZEBRA_SRU_HOST and "ZEBRA_SRU_BIBLIOS_PORT" set to. From an example, I think it's just the localhost & a different port (I used 8081).>>

Thanks, Lezlie
