Jquery validating radio button

[mayman212]

I am trying to validate radio buttons for gender using Jquery, but have no clue as to how I go about doing it, the different ways I've tried do not seem to work> anybody have any help.

I have included the form part for the gender radio buttons.

<tr>
		<td>Gender</td>
		<td><input type="radio" name="gender"value="Male" <?php if($row['Gender']=='male'){echo 'checked';}?>  /> Male<input type="radio" name="gender" value="Female" <?php if($row['Gender']=='female'){echo 'checked';}?>/> Female</td>
	  </tr>
