Adding to variable checkbox tick problem

2. There is no, "don't care". The cases will come up. I am guessing then that you mean that these cases do not count either way. You test for null (not answered) by using a condition: Variable equals (then leave third box blank). So you will need to have is an action that tests every group for not answered. See #6 below as to where to put this action.3. The tools page clearly showed that the radio buttons return whatever you name them. So, in your case it is a simple matter to name all the sets of the radio buttons as 1,2,2. Yes, just use those three numbers for the three names. You don't need any On Select/Change actions at all. You will need a pair of actions for each row. (See #6 for where to put these) To calculate your pairs: First row:Happened and planned: add 1 to S2; Condition: happened group 1 = 1 and planned group 1 = 1Happened and not planned: add 1 to S3; condition happened group 1 = 1 and planned group 1 = 2Second row:Happened and planned: add 1 to S2; Condition: happened group 2 = 1 and planned group 2 = 1Happened and not planned: add 1 to S3; condition happened group 2 = 1 and planned group 2 = 2etc.6. Sorry, missed the last post re. 2006. This makes the next step easier.Create a group - call it Compute-Group. Your first two actions on that button should be:S2 = 0S3 = 0 These will start you from a clean slate each time the button is clicked.Follow these with all the compute actions from #3 and display action. Since you recalculate S2 and S3 from scratch each time, you will have no duplicate counting.Then on your single button have the following actions:1. set a variable, say All-Answered, to "Not Okay".2. Check all groups for null (one action). But instead of displaying a message just yet, set All-Answered to Ok if all have a value. 3. Display error message if All-Answered = Not Okay.4. Run Action Group: Compute-Group if All-Answered = Ok.
