form doesn’t work

No matter what I do the form doesn’t work.

please tell me what I can do to fix this. I’ld like to have a working booking plugin.

I have the standard plugin plus the add-on subscription. It should be working.

I have a restaurant with all the settings in it and the for shows but no matter what date I put in it will not allow me to move on to the number of people.

thanks in advance for your information.
