I&#039m having trouble getting the code from the title article to work. I&#039ve created 3 ASP scripts: the first (WebFrame1.asp) with the FrameSet code; the second (ListBox1.asp) with the code to create a state ListBox and the JavaScript function HandleChange; the third (ListBox2.asp) with the states&#039 corresponding cities.<BR> When I change the state in the ListBox, the message &#039parent.frmListBox2.document&#039 is not an object.<BR> I pasted the code directly from the article and I&#039m running this from an NT Server with IIS 4.<BR> Any thoughts?
