Might be a silly question and I apologize in advance.
Wondering how to do this or if it is even possible
So I have :
field1 = field.char
field2 = field.char
field3 = field.char
I want field1 to populate onchange of field2 and field3 separated by a "-"
Fields are in the same form and the same model.
example
Name(field1): John - Smith
First name(field2): John
Last name(field3): Smith
