Can you give correct links so i can investigate the problem.
one thing that may be causing the issue is using "directions" as the form name, try using a different name for the form.
<form action="cincinnati_apiv3_2.php" method="get" name="directions">
also try changing the id of the "address" div:
<div id="address">
Oops.
cincinnati_apiv3.php and cincinnati_apiv3_2.php
Pretty bad when I misspell my home town. . .
Will try your suggestions and reply back.
ETA: No joy changing the div id or form name. . .
