sum(split({1,2,3},","))

replace {1,2,3} to pass the field you are referring to

*are you trying to save the values on differente record types or just one record type?

*what is the input values are you receiving on your field ? if comma its present.

for now I can give you a possible solution:

Rule: 

a!localVariables(
  local!textField, 
  {
    a!sectionLayout(
      contents: {}
    ),
    a!sectionLayout(
      label: "Field Values Into Record Types",
      contents: {
        a!textField(
          label: "Field",
          labelPosition: "ABOVE",
          value: local!textField,
          saveInto: local!textField,  
          refreshAfter: "UNFOCUS",
          validations: {}
        ),
        a!buttonArrayLayout(
          buttons: {
            a!buttonWidget(
              label: "Save",
              value: ri!theRecord,
              saveInto: a!save(ri!theRecord, length(split(local!textField, ","))), 
              submit: true,
              style: "OUTLINE"
            )
          },
          align: "START",
          marginBelow: "NONE"
        )
      }
    )
  }
)
