Select an option when a value comes preloaded

I have a form B with three fields that appears when I clicked the "send" button from another form A.

a!formLayout(
 label: "Form",
 contents: {
 a!textField(
 label: "City",
 labelPosition: "ABOVE",
 saveInto: {},
 refreshAfter: "UNFOCUS",
 validations: {}
 ),
 a!textField(
 label: "Office",
 labelPosition: "ABOVE",
 readOnly: true,
 refreshAfter: "UNFOCUS",
 validations: {},
 value: rule!CPRO_ER_getOffice(),
 saveInto: {
 a!save(ri!new.officeC,rule!CPRO_ER_getOffice())
 }
 ),
 a!radioButtonField(
 label: "Type",
 labelposition: "ABOVE",
 choiceLabels: {
 "car",
 "red",
 "urgency"
 },
 choiceValues: {
 "car",
 "red",
 "urgency"
 },
 value: {},
 saveInto: {},
 required: true
 
 ),
 },
 buttons: a!buttonLayout(
 primaryButtons: {
 a!buttonWidget(
 label: "Submit",
 submit: true,
 style: "PRIMARY"
 )
 }
 )
)

the value of the first field "city" is written by hand.
the value of the second field "office" can:
- Empty if it has been sent from the previous form
-be preloaded -> I want that when it comes preloaded directly select "urgency" from the "radiobutton".
                 If it comes empty, then you can choose any of the three options.
 
Thanks!
