finding and clicking a button on a webpage

[An_icehole]

My problem is this i need to click a button on a webpage which i can do but when its clicked it goes to another slightly different page so $oIE will be diferent and then i cannot find the same bottun because $oIE changes does anybody know how to find the address when you have been redirected after clicking a button

_IENavigate($oIE, "Web address")

_IEImgClick ($oIE, "giff that needs clicking", "src")

Sleep(2000)

rem at this point it goes to another address so _IEImgClick ($oIE, "giff that needs clicking", "src") will be looking in the wrong place i need to be able to read the new address and insert it into $oIE
