[LON-CAPA-users] Unordered Response Question Error

[Harding, Gene L]

Hi,

I am trying to embed some unordered numericalresponse parameters inside an xml table. I modeled my xml after the example in LON-CAPA, but am having two problems with it. The first problem is an error referring to tolerance range, and the second is incompatible units. This is a screenshot:

This is the code I am using:
<startouttext />
A $Pa dBm, $fa-MHz RF input signal and a $Pb dBm, $fb-MHz LO signal are applied to a nonlinear mixer with $Zin-Ω impedance. Complete the table of IF cross products for m,n equal 1,2.

<! Display numeric response inside a table >
<table style="width:400px" border="1" cellpadding="1" >
  <tr>
    <td> m </td>  <td> n </td>  <td> |mf<sub>a</sub> ± nf<sub>b</sub>| </td>  <td> Cross Products </td>
  </tr>
  <tr>
    <td>1</td>  <td>1</td>
    <td>
<numericalresponse format="0f" unit="MHz" id="11">
    <answergroup type="ordered">
        <answer type="unordered">
            <value>$fa</value>
            <value>$fb</value>
        </answer>
    </answergroup>
    <!responseparam name="tol" type="tolerance" default="0" description="Numerical Tolerance" />
    <textline size="8" readonly="no" />
    <textline size="8" readonly="no" />
</numericalresponse>
    </td>  <td>$f11_1 MHz $f11_2 MHz</td>
  </tr>
  <tr>
    <td>1</td>  <td>2</td>
  </tr>
  <tr>
    <td>2</td>  <td>1</td>
  </tr>
  <tr>
    <td>2</td>  <td>2</td>
  </tr>
</table>

<endouttext />

Any ideas why I am getting these two errors?

Thanks for any advice you can provide.
