Hi Nesa, so grateful for your help.
Almost there, not sure how to implement your last step, where or how to add script.
I have attached screen shots of the steps I followed and need help on the last one.
You are creating 'Radio Button' field and not a button as I suggested, it will still work the same but if you or users who will be using the form have highlights turned on they may not see the number under the Radio Button. I suggested 'Button' field because it doesn't have highlights, But if you still want to use 'Radio Button' script is same in both cases.
In field 'Properties' click on 'Actions' tab ⇾ Select Trigger: 'Mouse UP' and Select Action: 'Run a JavaScript', click on 'add' and paste script inside, look at photo bellow.
