Select Option to be removed after someone selects

Hi,  I am using Jotform to create a sign-up for an event and the restriction I would like is to have a person select a one hour time slot.  Once the slot is selected, it would be removed from the list for the next person.

For example: (As Drop-downs or radio buttons)

1:00PM

2:00PM

3:00PM

Then if the 2:00PM is selected by a user, the next person would see:

1:00PM

3:00PM

Is this possible?  And I'm using Square on here as well...  But I don't care how this can be achieved.  

Thank you!

Steve

If you're planning to use these selections with your Square payment integration, then you may consider using a widget, here are some of them that will help you to limit the available options that can be selected:

You will need to use your payment field to collect custom amount, the Form Calculation widget will be needed as well, here is a guide that will provide you more details about passing a calculated result to a payment field: How-to-Pass-a-Calculation-to-a-Payment-Field

Hope this helps.
