Conditional submit address on radio button selection

Having tried the above, it seems to swap out the value of the radio button and replaces it with the email address. What I want to be able to do was swap out the actual recipient of the email based on the radio button selected. i.e. if I selected the Year 2019 the email would be sent to [email protected] however, if I selected 2020 it would be sent to [email protected]
