Automatically Calculating Property Values
Once I have done the exercise "Automatically Calculating Property Values", in which we create a new property for calculating the total cost of coverage based on
the different plans selected in each category (medical, dental and vision), I made the next test:
1. In the medical coverage section, I select any plan. The total benefit cost is updated (let's say to $50).
2. Now, I decide to waive this coverage, so I check the "Waive medical benefits". The section is not visible, but the total benefit cost is still $50. In fact, I can see that the plan is still selected in the clipboard page...
3. I click the submit button, so I go to the next step (Dental benefits). The total benefit cost is still $50.
4. I select a plan and the cost (let's say $25) is added to the total benefit cost, which is $75 now...
So, I tried to improve this in order that if I select a plan, and I waive it later, the plan is not selected anymore and, therefore, the total cost is updated again. BUT, I didn't get it, and I did not know how to do it...
I'd like to know how to solve this. I think it's the better way to learn.
Thank you!

The most elegant solution is to revise the Data Model to use a Page Group for Benefits.
You could then define a Rule-Declare-Expression that says:
Total Benefit Cost = Sum of .Benefit().Cost using entries which .Waived = false
Otherwise you have to resort to other mechanisms.
You may need to define a new Property for every Benefit named ".CostAddedToTotal".
Possibilities:
1) Define a Declare On-Change rule for .Waived. If the value is true, set .CostAddedToTotal to 0. If set to false set equal to Plan cost for that benefit. Sum each .CostAddedToTotal value.
2) Have the Total Cost R-D-E call a Decision table that evaluates all rows. .Waived is an input column for each Benefit. If .Waived is true do not add anything to Total Benefit Cost.
3) Define an R-D-E that sets .CostAddedToTotal to zero if .Waived - true otherwise set equal to the plan cost for that benefit. Sum each .CostAddedToTotal value.
