You should use two equations to define the two values
like
eq1: {if(is_empty(eq1),rand(1,5),eq1)}
eq2: {if(is_empty(eq1),rand(1,5),eq2)}
And in your question text
Code:
<table>
<tbody>
<tr>
<th>Factor</th>
<th>Value</th>
</tr>
<tr>
<td>Street lighting</td>
<td>{eq1}</td>
</tr>
<tr>
<td>Density</td>
<td>{eq2}</td>
</tr>
</tbody>
</table>
So you will find the values in the csv-file
"id","submitdate","lastpage","startlanguage","seed",
"eq1","eq2","boilerplate1"
"2","1980-01-01 00:00:00","2","en","583167754",
"5","3",""
