How to select 1 radio when having 2 groups of radio

Hi
I have a form for restaurant reservation with 2 groups of radio buttons
first group for lunch and second group for diner and i need to be sure that the user select only 1 radio (from diner options or lunch options) so it is not possible that the user select option in both of the radio groups.

Im using this code:
Lunch
[radio your-time-reservation-lunch use_label_element “12:00” “12:15” “12:30” “12:45” “13:00” “13:15” “13:30” “13:45”]

Diner
[radio your-time-reservation-dinner use_label_element “19:00” “19:15” “19:30” “19:45” “20:00” “20:15” “20:30” “20:45”]

Please help.

Thanks
