Hi Ashish,
As mentioned in the forum post -
https://portal.smartbuilder.com/web/smartbuilder/forum/-/message_boards/message/446692#_19_message_447538We have some new features that are due out in next release (should be in the next couple weeks) that might help with this logic, specifically a block that can tell the tell you how many options have been selected in a Checkbox group. So you might want to wait for that.
Currently you would have to create a series of conditions to manually check and see if each option is selected and add that to a variable. It'll be much easier if you can wait for the update.
