Answer 1

你把相同的ID在兩個輸入欄

<div class="field_radio" name="preference"> 
    <input class="radio1" type="radio" name="preference" id="preference_one"   value="team" onclick="ShowHideDiv()" /> 
    <input class="radio2" type="radio" name="preference" id="preference_two" 
    value="individual" onclick="ShowHideDiv()" /> 
</div> 

Answer 2

<div class="field_radio"> 
    <input type="radio" class="radio1" name="preference" id="preference1" value="team" onclick="ShowHideDiv()" /> 
    <label for="radio1"><span>Team</span></label> 
    <input type="radio" class="radio2" name="preference" id="preference2" value="individual" onclick="ShowHideDiv()" /> 
    <label for="radio2"><span>Individual</span></label> 
</div> 

注：單選按鈕的ID是相同使它不同會解決你的問題！
