Simulate click on radio button

[longphant]

<input id="one" onclick="JavaScript:selectPage('1')" name="theRadio" CHECKED="checked" type="radio"><label for="one">One</label>
<input id="two" onclick="JavaScript:selectPage('3')" name="theRadio" type="radio"><label for="two">Two</label>

How can I simulate click on Two?

I have tried _IEFormElementRadioSelect (but there is no value or index field). I also tried

$radio = _IEFormElementGetObjByName($oForm, "theRadio") but I get a warning that "--> IE.au3 V2.4-0 Warning from function _IEFormElementGetObjByName, $_IEStatus_NoMatch"

Anyone have any ideas?
