HTML form doesn't run in browser window

I have a simple HTML form that inputs your postal/zip code and calls Google Maps to create a route from your location to a hard coded destination.

At my development site brutus.dalnet.ca/wordpress it works properly. If you go to the site and select menu item “Our Activities” and then “2015” you are presented with a page showing dates, events, locations etc.

If you click on “Click for Directions” under Tavistock Fair Grounds it presents a page asking for your postal code. Once entered, click on GO and it creates a nice Google map from your location to Tavistock Ontario.

At my live site, ontarioairstream.wbcci.net if you follow the same procedure, the browser window just lists the HTML form code and doesn’t execute.

Now ontarioairstream is a multisite setup so perhaps that has something to do with this problem.

I don’t believe that I did anything special on my development site to have this working.

Any thoughts or suggestions would be most welcome.

Thanks… Tom.
