reference the variable to default value

Is there a way to reference the variable from the previous question using ${ } such that this reference is the default value of the next question.
What I am trying to accomplish is that I am using pulldata function to get the value from the csv file and then I need to set this value as a default selection in the single select dropdown. If I set the default value using the ${} it does not works(i.e the value is not shown selected), but if I hard-code the default value then the default selection is shown.

The example at XLSForm worked for me, but I am trying to set as a default value instead of the one shown in the example.

Is this not possible with kobotoolbox?

Thanks.
