Can we show a passing/failing score and not allow submission based on it as well?

I am trying to create a Checklist form for assessing our Clinic appearance. I would like to be able to make rules on the calculation of the form. I want to make each multiple choice answer worth points that are then tallied and divided by the possible total score to create a percentage score. However, I would also like one of the mulitple choices, if chosen on any of the questions, to make it impossible for them to pass despite the percentage score.

For example:

Answers:

Meets = 5 points

Issue A not meets = 4 pts

Issue B not meets = 3 pts

Issue C not meets = 2 pts

Issue D not meets = 1 pt

Passing score is above 80% AND with no Issue D's 

You could do that with a bit of conditions and calculation values.

Basically the conditions can be used to check if some of the options were clicked and then hide the submit button, or show them some notification, etc, while the calculation values will help you to determine the percentage.

Calculations value can be added as shown here: How to Assign Calculation Value

Which you will then capture with Form Calculation widget.

You can also see a bit about the conditions by taking a look here:

I would also recommend checking out this thread if you are going to check several fields for the same value: How to Find The OR operator in conditions? since you would be using AND operand (ALL option).

Do let us know if you have any difficulties setting it all up.
