List Box not accepting change

there is a list box that changes what you see on the website according to what is selected. here is the coding im using

$oIE = _IECreate("http://football.fantasysports.yahoo.com/f1/147955/editdraftresults")
;$oIE = _IEAttach("http://football.fantasysports.yahoo.com/f1/147955/editdraftresults")

Local $Form = _IEGetObjById($oIE, "ysf-customdraftresults-form") 
Local $Select = _IEFormElementGetObjByName($Form, "newtid")
_IEFormElementOptionSelect($Select, "Couto's Team", 1, "byText")

It works just as it should it puts the list box on the item i want but the rest of the website doesn't change as it should until i actually go in with my mouse and click and select a different item. Is there something im missing?
