Question:
How can I enable the selection of more than one OptionButton per screen?
Solution:
To do so, you need to set different values in every OptionButton’s GroupName property. For example, on a screen with four OptionButtons:
- OptionButton1 – GroupName: Group1
 - OptionButton2 – GroupName: Group1
 - OptionButton3 – GroupName: Group2
 - OptionButton4 – GroupName: Group2
 
With these settings, you can select: 
(OptionButton1 OR OptionButton2) AND (OptionButton3 OR OptionButton4)
In a GroupName, you can select only one OptionButton. So, you can edit the GroupName to create different groups and enable selecting more than one OptionButton per screen.
