Adding variable values together (total) without continually adding

Hi Tony, 

You can count the score not according to changes in these four variables but based on a new variable (let's call it 'Makingoptions') changes.

Detecting variable changes by four triggers:
Add value 1 to Makingoptions when (your four variables) changes

Recount the total score by five triggers:
1.Set CPOTCalculator to 0 when Makingoptions changes
2.Add(your four variables values) to CPOTCalculator when Makingoptions changes
