Right, so I have thing thing where I want to use variables and conditionals to use in a prototype where a user would select:

• 0 checkboxes and then select Button and get error message saying you need to agree to both checkboxes
• 1 checkbox and get error message saying you need to agree to both checkboxes
• 1 checkbox (the other one) and get error message saying you need to agree to both checkboxes
• 2 checkboxes and then move on to checkout flow

The checkboxes should be easy to toggle between active/inactive.

When the button is selected and the error message appears, I need the checkboxes to show error (red outline) if inactive.

Anyone done this or seen a tutorial on it? I tried so many different things in Figma, did it in Axure in 10 minutes and ended up drinking  whiskey instead.

Thank you in advance for your time.
