How do I limit the attendee to selecting only one choice?

On my form (2017 MCMGA Registration Form) I have a choice of lunches located directly below the text that describes the box lunches.  Since the lunch will be included in the registration fee, I've pulled it out of the area below where Paypal calculates the total cost of registration and merchandise items.  How do I limit the attendee to selecting only one choice vice allowing them to select multiple lunches?  Right know I can check mark a turkey breast and ham & swiss lunch box.  But the intent is for them to only select one?  I would like it to toggle from one or the other or if double checked, then none.

thank you.

I can see that you are using a Multiple Choice or Check Box field.

Please use the Single Choice or Radio Button field instead.

Hope that helps. Thank you.
