I do have two optionsgroups Group1 and Group2.
Each optiongroups has three option with value 1, 2 and 3.
I have one total field, which calculates the sum of Group1 + Group2.
This function is not correct. It calculates always wrong values.
Check the attached PDF and click on the option boxes, you will see, that the result (just the sum of two values) is wrong.
I also attached some screenshots (left = Group1 with values 1,2,3 from up to down and right is Groupbox2 with 1,2,3 from up to down) and the calculated results :-(
