Answer 1

Your HTML markup has an error

<a href="http://www.hobbylobby.com/storelocator"/>

It should be

<a href="http://www.hobbylobby.com/storelocator">

Also try

<form method="POST" action="">

Keeping the action blank will post it to the same page itself

And replace your submit button with this

<input class="dealer-submit" type="submit" name="submit" value="Submit" onClick="buy_func()"/>
