Showing data from combo field into another text field

[Lele]

Hi there,

 

I have a desire, I hope to be able to explain you my question.

I have a field with combo options (3x options: option 1 gives value 10; option 2 gives value 14; option 3 gives value 18), so I also have a text field where I need it is shown the value given from that combo field.

So the result should be:

- when I choose option 1 in combo field then text field shows 10

- when I choose option 2 in combo field then text field shows 14

- when I choose option 3 in combo field then text field shows 18

Is it possible? How ?

:-)
