There are 2 way around the problem both ugly.
First keep two copies of the test condition So you have ValueA and ValueB both set the same. Now you test
Line:"Between 10 and 20" {"check":{"valueA":">10"},{"valueB":"<20"}}
The second way is even uglier...
Line:"[Line20]"{"check":{"Value":">10"}}
Line20:"Between 10 and 20"{"check":{"Value":"<20"}}
Line20:"Probably need to have a line to catch >20 lines"
