JotForm is a free online form builder which helps you create online forms without writing a single line of code. No sign-up required.
We believe that if one user has a question, there could be more users who may have the same question. This is why many of our support forum threads are public and available to be searched and viewed. If you’d like help immediately, feel free to search for a similar question, or submit your question or concern.
The only solution I could think of for this is to create a separate form, one for 10 people to serve dinner, and then another form for 5 people to bus tables.
And then you can limit the number of submissions your form can receive by enabling the submissions limit by the number of submissions. You can read on this user guide in order to understand this option: https://www.jotform.com/help/137-How-to-limit-submissions-in-a-form
Next, you can add the submissions counter widget to your form to show the number of spots filled or number of spots available
If you have further questions, please let us know.
Let me offer an alternative solution.
The needed number of servers or bussers can be seen immediately once the form loads. This demo only allows 1 option (server or busser) to be chosen per transaction or person.
Hope this helps.
