Hi gilg67
You should follow template documentation HERE
You should add extrafields for your k2 items
latitude
longitude
all your categories should have as main category the default directory cat -
also verify if you have installed the ja k2 extrafields plugin
To receive help from us would be better if you will publish your website on a public forum , we cannot debug your localhost settings so the only help we can provide in such cases is to follow documentation page -
Regards
