[jQuery] Validate. Not working with Radio input


Hello,
I am trying to validate a form with radio inputs. I want to the form
to be submitted only if an option was selected:
<form action="/Poll/Vote/1" class="Poll" id="Poll" method="post">
<fieldset>
<label for="OptionsArray">Do you like to travel?</label>
<input type="radio" name="OptionsArray" id="1" value="1"
class="Radio" />
<label for="1">Yes</label>
<input type="radio" name="OptionsArray" id="2" value="2"
class="Radio" />
<label for="2">No</label>
<input id="Submit" name="Submit" type="submit" value="Vote" /
