Forms :: Highlight To Update Form?

I have a form that I need to update whenever a chosen business name changes. This is tied to a search function that updates/changes the business name, and this works fine. What I now need it to do is when the name is clicked on the table (which updates the respective business name) I need everything else to update with it.

I have tried refreshing the business name, the form, even the records themselves with onClick and onChange functions, but it still doesn't work.

Re-reading this I realize it doesn't make much sense, but hopefully the attached database will clear things up. When you type in the info in the search box, all the stuff in the right corner changes accordingly. If you click and highlight anything in the box in the center instead of using the search function, the business name at the bottom changes but everything in the right corner remains unchanged.
