repeating section questions

[andrew]

I am trying to convert a list of elements into a list of option button
selections... here is the data I'm working with...

<Employee>
<EmployeeID>1</EmployeeID>
<Name>Joe Smith</Name>
</Employee>
<Employee>
<EmployeeID>2</EmployeeID>
<Name>Chris Brown</Name>
</Employee>
<Employee>
<EmployeeID>3</EmployeeID>
<Name>Susan Jones</Name>
</Employee>

I am having a few issues.

1. Even though I have not selected "allow users to insert and delete the
sections" in Repeating Section >> Data >> Default Settings... I get an
"insert item" link at the bottom of my Repeating Section when I do a preview.

2. I can't figure out how to treat the option buttons as a group of option
buttons... aka only one can be checked out of the group.
