How Can i Fill the Text Box In IE?

[naru]

#include <IE.au3>
$oIE=_IECreate("https://acc.rollernet.us")
$oObj = _IEGetObjByName($oIE,"username")
_IEPropertySet($oObj,"innertext","MyUserId")
$oObj = _IEGetObjByName($oIE,"password")
_IEPropertySet($oObj,"innertext","MyPassword")
$oObj = _IEGetObjByName($oIE,"submit")
_IEAction($oObj,"click")
Exit
