Hi everyone. I'm reaching out again for your help to implement this aspect of my project. I still haven't received a response. The issue of treatment assignment has already been discussed but does not pertain to my approach.

Here are the constants from the form that appear in the texts. The idea is to assign randomly a participant to a treatment group and have the constants included in the texts take the values relative to the treatment in question. The relevant constants are {{ RATIO }}, {{ LOWER }}, and {{ UPPER }}.

          T1     T2     T3    T4
Average   80     80    160    2X 
Ratio     3      9       9     3
Lower     40     16     32     X
Upper     120    144   288    3X
