Issue while converting value to upper case

Hi,

I am trying to convert the text which is entering into the textField into a upper case and trying to store into a ruleInput.

But, it is not working as expected. I am attaching the code here to get some experts advise. Thanks.

a!localVariables(
  {
    a!columnsLayout(
      columns: a!columnLayout(
        contents: a!textField(
          label: "Name:",
          value: upper(ri!name),
          saveInto: upper(ri!name)
        )
      )
    )
  }
)
