This tag is what is used to create the window within a window effect, the frame in which this document shows up.
Note that its name is scriptwindow, and that a page (called js0000.html) is loaded into the frame right at the start. Later if you want to put something there, include the target="scriptwindow" attribute in your link or form-input tag. Then the document will be placed where the IFRAME tag ison the page.



<IFRAME name="scriptwindow" 
src="js0000.html"
width="480"
height="500"
scrolling="auto"
frameborder="0">
</IFRAME>

You don't have to call it scriptwindow, that is just the name I used for the moment, but it must be consistent with the rest of your code.
