    There are <span class='class_num_box'></span> boxes in the <b>{{ participant.valence }} task</b>. Each box contains a <b>{{ participant.valence }} amount between ${{ C.START_VALUE }} and ${{ C.END_VALUE }}</b>. 
</p>

<div class="alert alert-info" role="alert">
  <b>Your task is it to open some of these boxes to determine a {{ if participant.valence == 'bonus' }} bonus that will be added to your balance{{ else}} penalty that will be taken away from your balance{{ endif }}.</b>
</div>

<p>
    The closer you get to finding the {{ if participant.valence == 'bonus' }} largest bonus,{{ else}} smallest penalty,{{ endif }} the larger your balance will be after completing the {{ participant.valence }} task.
</p>

<p>
    The graph below shows the number of boxes that contain each {{ participant.valence }} amount.
