Subject Re: Data from generator to multiple frames
Date Wed, 29 Sep 2004 22:45:17 GMT
Thanks for your help.  I think that I am going to have to make another
request of the data for this to work.
I am tasked with displaying the images in an xml data module in a different
frame than the text within the
same module (at the same time as the text of course).
