How to clear field value after the field is disabled

a!localVariables(
  local!field1,
  local!field2,
  {
    a!cardLayout(
      contents: {
        a!radioButtonField(
          choiceLabels: { "Yes", "No" },
          choiceValues: { 1, 2 },
          label: "Radio Buttons",
          labelPosition: "ABOVE",
          value: local!field1,
          saveInto: {
            local!field1,
            if(
              and(
                local!field1 = 2,
                a!isNotNullOrEmpty(local!field1)
              ),
              a!save(local!field2, null),
              ""
            )
          },
          choiceLayout: "STACKED",
          validations: {}
        ),
        a!integerField(
          label: "Integer",
          labelPosition: "ABOVE",
          value: local!field2,
          saveInto: { local!field2 },
          refreshAfter: "UNFOCUS",
          validations: {},
          disabled:if(a!isNotNullOrEmpty(local!field1),
          local!field1=2,null)
        )
      },
      height: "AUTO",
      style: "TRANSPARENT",
      marginBelow: "STANDARD"
    )
  }
)

Write save on field 1 that makes field2 value null. Have a look into the sample code .
