Radio button - print info in email

I want to write function that takes the true or false answer of radio button and prints information into an email to send via corona. 

radio button: 

local checkboxButton = widget.newSwitch

    {

        label = “qTwo”,

        left = 555,

        top = 100,

        style = “checkbox”,

        id = “questionTwo”,

        onPress = onSwitchPress

    }

        scene.view:insert(checkboxButton)

down in the email section(email works):

subject = function() 

                if checkboxButton.switch.isOn == true 

                    then    print(“qTwo here”)

                    

                end

               end
