Hello, we want to create teams of three based on a number the players have first entered. So in short, this is what happens: 1. Players move a slider from 0 to 500 and then enter the number they land on. (This code is complete) 2. The numbers are sorted from smallest to largest and then the three players who have entered the lowest three numbers are assigned to team 1, the next three numbers and the players who chose them are team 2 and so on. We are stuck on the second step. Does anyone have any idea how this could be done? Any advice is highly appreciated! Greetings Caro

Hi, you mention team 1 or team 2, is it means a Group? assume that, there are 9 players and each choose a number. the code may like this ``` from otree.api import Page, WaitPage from .models import Constants class ChooseNumber(Page): form_model = 'player' form_fields = ['number'] class ResultsWaitPage(WaitPage): after_all_players_arrive = 'set_payoffs' class DisplaySortedNumbers(Page): def vars_for_template(player): # get all numbers and sorted numbers = sorted([p.number for p in player.group.get_players()]) # divided to groups group_size = len(numbers) // 3 groups = [numbers[i:i + group_size] for i in range(0, len(numbers), group_size)] return { 'sorted_numbers': numbers, 'groups': groups } page_sequence = [ChooseNumber, ResultsWaitPage, DisplaySortedNumbers] ``` Thanks, Tina https://otree.xindamate.xyz/en/

Hi, I've created a demo project for you. Here's the demo link: http://42.193.99.75:8008/demo. and here is the Github code Repo https://github.com/The-Three-Fish/two-app In the demo, "app1" allows you to choose a number, and "app2" uses the value to divide it into 3 groups. You can test both by selecting "app1app2" to see if the effects meet your expectations. Thanks, Tina https://otree.xindamate.xyz/en/
