Programming an inspection form

I am creating an inspection form and would like checkboxes to populate based on the value of another box. For example, the Total Score of the inspection would, based on its value, allow a checkbox to populate whether the inspection is Green, Amber, or Red.

Also, I would like that when a checkbox is checked, it populates the associated point value for that section that then translates to the overall assessment area.

I know this is a lot to ask but Googling the answers doesn't seem to be helping me.

Thank you in advance for any and all assistance.
