<form action="">
<input type="radio" name="sex" value="male">Male
<input type="radio" name="sex" value="female">Female

So the radio buttons with various values might now instead post to names such as EmployeeType_2 and EmployeeType_3.
This is essentially what will happen behind the scenes when you try to do code like the following.
