Screen - Radio Button

Hi,

I have a screen, where I have two radio buttons and input fields in front of them.

I want to make the input fields of one Radio button invisble when the other is selected.

However, when I select the radio button, I have to press Enter to make the input fields visible again.

I want the fields to be visible when the Radio button is selected.Is it possible to do so.

Please suggest.

Thanks in advance,

Archana
