Field input through a Radio button

Hi

I am trying to make a field in a form, which will display some amounts depending on the radio button selected.

For example: If there are two radio buttons, with one has value of $200 and the other $300. So if someone clicks on $200, the field on the form should show $200 and then if someone clicks on $300, the value in the field should change to $300 and vice versa.

make the second field computed, and set the formula to be the name of the radio button field. Set the radio button field’s properties to Refresh Fields on Keyword Change.
