Cannot fire this dropdown though I can change it's value

#include <ie.au3>
 
Local $oIE = _IEAttach("Account Activity")
Local $oForm = _IEFormGetCollection($oIE,0)
Local $oSelect = _IEGetObjById($oForm,"StatementPeriodQuick")
; Any of these 3 methods work to select the 5th item "All Transactions"
_IEFormElementOptionSelect($oSelect,"ALL",1,"byValue",1)
_IEFormElementOptionSelect($oSelect,"All Transactions",1,"byText",1)
_IEFormElementOptionSelect($oSelect,"4",1,"byIndex",1)
 
;Nothing happens when I try any of the following
_IEAction($oSelect, "focus")
$oSelect.fireEvent("onSelect")
$oSelect.fireEvent("onselectstart")
$oSelect.fireEvent("onchange")
$oSelect.fireEvent("onclick")
$oSelect.fireEvent("onmousedown")
$oSelect.fireEvent("onmouseup")
 
;Submitting the form just refreshes the page with the defaults
;_IEFormSubmit($oForm)
