In the checkout settings (Commerce > Checkout) you'll find a setting called "Let Customers Buy Multiple Service Products". If the tickets have been configured as Service Products and you uncheck this box, the customer will only be able to add one ticket at a time. Each time they click/tap the Add to Cart button (or whatever you have captioned it) they will be prompted again with your form, and be able to add a name.

For a good user experience, users should clearly understand what happens when they click the "add" button so when using this configuration it is a good idea to change the button's caption and add some additional messaging that explains how to add multiple tickets.
UPDATE:
In 2024, this checkbox was changed to "Quantity for services" and can be found in Settings > Selling > Checkout:

SS doesn't have anything built-in to handle this particular situation. So just about anything we could come up with will have pros and cons.
You could add a number of non required name fields. The number would have to be such to cover most situations. But if you think someone might go over, then you could add a free form text field where extra names could be added.
If you use required fields that would be a problem as they would all have to be filled out.
Also note that there is no built-in way to link the quantity field to what is happening in the form.
Now with a business plan or above and some custom coding it may be possible to come up with something a little more structured but again what can be done is limited to what can be done on the browser side of things. Nothing can be done to change how SS handle forms on the backend.

That was it! Thanks for the share, I'll keep this in mind for future builds! 
My Countdown clock on the homepage still disappears when it wants... but the rest of the pages are cooperating, so I'm not going to push my luck. hahaha. 🤣
Thanks again @creedon

I'm thinking the curse of Ajax Loading strikes again! Try turning off Ajax Loading to see if the problem goes away.
Please note that turning off Ajax Loading will affect the performance of your site. Ajax Loading is designed to increase the loading speed of your site after it first loads.
You have to decide whether the custom code you are trying to use is worth turning off Ajax Loading.
paul2009 has a great article on the ins and outs of Ajax Loading. Please see Why does Squarespace code only work on refresh?

I would like to display the day of the week (in all caps) in front of my dates on my event summary pages. i.e. THURSDAY, February 3, 2022
I am currently using this code on the actual events page in the Page Header Code Injection, but its not capitalizing the days or carrying over to the summary pages.
Am I putting it in the wrong place? Do I need to add additional code? and if so, where? 
I'm on brine 7.0.
<style> var d = new Date(); var days = ["SUNDAY", "MONDAY", "TUESDAY", "WEDNESDAY", "THURSDAY", "FRIDAY", "SATURDAY"]; var months = ["January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December"]; document.getElementById("demo").innerHTML = days[d.getDay()] + " " + months[d.getMonth()] + " " + d.getDate() + " " + d.getFullYear(); </style>  
 

Works like a charm. Thank you very much!
