[LON-CAPA-users] Unordered Response Question Error

Hi Carl,

The ! was commenting out the parameter, something I tried among several permutations of syntax hoping to get something to work. The error message is the same whether it is there or commented out. I originally also had a sig figs param in it, but deleted it. I think that eliminated one error.

I have tried putting the unit= and format= in the answer and value fields, but no luck there, either.

not sure of the impact of the ! in the responseparam field. I believe you should have some tolerance if you have a calculated real number, e.g.

<responseparam name="tol" type="tolerance" default="2%" description="Numerical Tolerance" />

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:
[cid:image001.jpg at 01D2761B.10017050]

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" >
    <td> m </td>  <td> n </td>  <td> |mf<sub>a</sub> ± nf<sub>b</sub>| </td>  <td> Cross Products </td>
    <td>1</td>  <td>1</td>
<numericalresponse format="0f" unit="MHz" id="11">
    <answergroup type="ordered">
        <answer type="unordered">
    <!responseparam name="tol" type="tolerance" default="0" description="Numerical Tolerance" />
    <textline size="8" readonly="no" />
    <textline size="8" readonly="no" />
    </td>  <td>$f11_1 MHz $f11_2 MHz</td>
    <td>1</td>  <td>2</td>
    <td>2</td>  <td>1</td>
    <td>2</td>  <td>2</td>

<endouttext />

Any ideas why I am getting these two errors?

Thanks for any advice you can provide.
