FORM dropdown list from script

[FiGi]

Hi,

I have a little problem going through a form that looks like this:

I can easily select what i want from the 3 option lists on the left

$oForm = _IEFormGetObjByName ($oIE, "rejestrowanie")
$oSelect = _IEFormElementGetObjByName ($oForm, "lista_klient")
_IEFormElementOptionselect ($oSelect, "745")

, but the options list on the right is built with a script:

poz = 1;
        czynnosc.options.length = poz;
        for (key in czynnoscArray)
        {

                  czynnosc.options.length = poz+1;
                  czynnosc.options[poz].text = czynnoscArray[key];
                  czynnosc.options[poz].value = key;
                  poz++;

        }


        if(lista_grupa.selectedIndex!=0)
        {

and using the same method as above it just doesn't work

Can anyone help me with this? ...Thanks in advance

That would probably be a good idea. Can you provide a link to the page or at least the generated source.
