onClick does not work when user clicks "back"
<p>I have form elements that determine the action of the form like below.  This works great EXCEPT when they click the back button in their browser and it forgets the action.  What is the best way to fix this?</p>

<pre><code>&lt;label&gt;
    &lt;input type="radio" name="proptype" id="RESI" value="RESI" checked="checked" onClick="this.form.action='?frame=TEST&amp;base=fc';" /&gt;
                Residential&lt;/label&gt;
&lt;label&gt;
    &lt;input type="radio" name="proptype" id="LOTL" value="LOTL" onClick="this.form.action='?frame=TEST1&amp;base=fc';" /&gt;
                Land and Lots&lt;/label&gt;
</code></pre>
