[Plugin: Simple Real Estate Pack] Multiple zip codes

Hello – I am inserting the shortcode for the schools in a particular community. I’d like to get multiple zip codes to appear cleanly. Any suggestions? I cant search by city because these are unincorporated areas.

I’ve tried:
[schoolsearch state=”CA” zip=”12345, 12346″ groupby=”gradelevel” output=”table”]
[schoolsearch state=”CA” zip=”12345,12346″ groupby=”gradelevel” output=”table”]
[schoolsearch state=”CA” zip=”12345″ zip=”12346″ groupby=”gradelevel” output=”table”]

I’ve even tried just using the standard shortcode in two seperate lines – one for each zip code… but, for some reason, it doesnt show very cleanly at all.

Any suggestions?
