Conditional logic with radio buttons

I have a registration form which allows users to select the type of membership they require.

I want some of the registration fields to display conditionally, depending on the option set in the radio buttons for the Type of membership field.

The options for the radio button are:

• Individual (￡10)
• Individual – Student (￡5)
• Group – School (￡80)
• Group – Early Years or Nursery (￡50)

I have set up conditional rules like this:

show if type of membership contains Group

and

show if type of membership contains Individual

The rules do not work and none of my conditional fields are displaying.

Any suggestions hugely appreciated.

Thanks

Stephen
