Hi, 

I would like to add a variable to the label of another formfield. It works if it's only the variable (see Template below), but I would like to nest it into a sentence (see Template1 below). Obviously, I get an error. I've tried already many alternatives, but couldn't find a solution. Any ideas are very welcome (: Thanks

models.py:
class Player(BasePlayer):
         guess_upside = models.PositiveIntegerField()
         prob_upside = models.PositiveIntegerField()

Template:
{{ formfield 'prob_upside' label=player.guess_upside}}

Template1:
{{ formfield 'prob_upside' label=Why did you guess player.guess_upside?}}

Hi Chris,

thanks a lot for your reply. However, there is another issue now.
I would like to use the input variable from another precedent app. 
Following the documentation, I put

@staticmethod
    def vars_for_template(player):
        return dict(
            criteria_label='Why did you choose'.format(player.participant.guess_upside)
        )
        
but the actual page only shows "Why did you choose" without adding the value for guess_upside variable.

Do you have an idea how to solve that?

Thanks in advance,
Frieder
