Can't get switches to work on form

can’t seem to get switches to work at the end of the form, so customer can choose how to be contacted. the buttons are greyed out and you cant click on them,

see photo. appreciate your help. thanks

They should work in Preview. They wont in design.

I have managed to get them to work, i had to change the ID to ‘optin1’ ‘optin2’ ‘optin3’

when i get the email it says true or false for each one

Larn, you may like to make the fact that you only cover postcodes NN1 to NN6 more prominent, probably on your home page. Otherwise people are going to have to delve deep to find it.
