We have 10 options which are time slots. Each time slot has four openings.  That is a total of 40 openings for the day. 

What we want to do is remove the time slot from the radio button list once all four opening have then selected (submitted).

While we can tell people the option is full when they submit the form via script, we are looking for a script that will remove the option from the list once full.

Thanks in advance for your guidance and expertise!
