I have 2 different modules:
Module A has 3 fields.
-Points payable: 300
-Points balance: -100(i want it to deduct the "points payable" from "points",)
-Points:200(it to be hidden)
However for my "Points", i want to retrieve it firstly from Module B, then updates Module B's "points" from here.
Module B has 1 field.
Points:200(update from hidden field in Module A)
Is it possible to do this? May i have the steps please?
