In my game, I have two variables (tax and public good provision). The maximum level of public good provision should be smaller than the tax amount. I am using the {field_name}_max() function to achieve this goal. However, it seems that the code does not work. It would not generate error message accordingly. Here are my codes: class Player(BasePlayer): pga = models.IntegerField(min=1, max=100, label="Public Good Provision: ") pgb = models.IntegerField(min=1, max=100, label="Public Good Provision: ") taxa = models.IntegerField(min=1, max=100, label="Tax Amount: ") taxb = models.IntegerField(min=1, max=100, label="Tax Amount: ") def pga_max(player): return player.taxa def pgb_max(player): return player.taxb def pga_error_message(player, value): print('Public good level is', value) if value > player.taxa: return 'Cannot offer public good more than your tax budget. ' The error seems related to player.taxa is null. Many thanks for your help!

It seems that this error has something to do with the player.role I use. I have used 7 player roles. Please see attached my codes. Many thanks for your help!
