Sure, here is the XML file...
You may need to change around the user fields to get everything working correctly.
Also note, I made a field for enabling the drop down:
Code:
<vb:if condition="$post['field6']=='Yes'">
It is just a yes/no single option box.
I did this so that the first field didn't have to be filled to show the drop down.
If you have any questions feel free to ask.
