[Javascript] Controling a SELECT from a child window

[Dstoltz at SHH.ORG (David Stoltz)]

Hi All,

I have a problem - I am popping up a child window, and I need to:

1) Clear a select box on the parent of all it's options
2) Add new options to the select box on the parent window
3) Select (highlight) an option in the select box on the parent window

Can anyone give me any code how I can do this from the CHILD window? I
am trying with this so far to select an option, with no luck:

window.opener.document.form1.mylist.option[0].selected=true;

Thanks for any help
