Many thanks for your quick response. I followed the instructions and tried to filter the data but, although I can get a drop down list for "Activity", my drop down box for "Analysis" is empty when I input a choice in the Activity. Here is a snippet of the *xml.document I am trying to use...
<Data>
<Activity value="Type A">
<Analysis value="Analysis A"/>
<Analysis value="Analysis B"/>
</Activity>
<Activity value="Type B">
<Analysis value="Analysis Y"/>
<Analysis value="Analysis Z"/>
</Activity>
</Data>
Any thoughts on what I am doing wrong?
Thanks in anticipation
