How to I limit a checkbox field to one choice? I am using a checkbox field to capture a 'Y' or 'N' value. This works just fine unless the user checks both boxes. I tried a couple validation rules on the field but none have worked so far. Any suggestions?

a!checkboxField(
label: "Certification Required?",
labelPosition: "ABOVE",
choicelabels: {
"Yes",
"No"
},
choiceValues: {
"Y",
"N"
},
value: ri!newAgreement_cdt.certRequired,
saveInto: ri!selectedAgreement_cdt.certRequire
),

)),
a!save(local!checkboxSave,
local!checkboxValue
)

}
),
a!textField(
label: "Display value: user will have to click away to see second selection disappear",
value: local!checkboxValue,
readOnly: true
),
a!textField(
label: "Saved Value",
value: local!checkboxSave,
readOnly: true
)

})
)
