Combining two text fields in a form

[Guest]

I have created a form with 'Physician First Name' and 'Physician Last Name'; how can I get a new field 'Physician Name' to generate automatically combining the first and last name fields once information has been entered into each field?

Use this code as its custom calculation script:

event.value = this.getField("'Physician First Name").valueAsString + " " + this.getField("'Physician Last Name").valueAsString;
