kirkward on "Aggregating Usermeta From Blogs To Custom Table"

I am working to build a plugin or an MySQL query to aggregate some blog and user meta into a table created by a plugin. The plugin developer has advised me that the table is a flat table, and I can add data to it.

I am using code I found through web search (Google) and have verified that I am retrieving the data I want to use by echoing it to screen.

I have slightly modified the code that displayed the data in an attempt to insert that data into the plugin table wp_store_locator.

It doesn't work. And as you can understand, because I am posting here, I haven't got the faintest clue on how to make corrections.

Any suggestions?

Thanks,
Kirk
