    So I am trying to get help with the widget ticket purchases 

    It works perfectly but I am having one issue

    is it possible to have the form, once the submit button is hit, to recheck the ticket purchases widget to make sure there spots are available before submitting 

    reason being because, lets say there is one spot left in a class, but two users open the form at the same time, if the first user completes the form and submits, it should make the spot unavailable for the second user but for some reason the user is still able to submit the form with the sold out spot because it only updates if the form us refreshed or the form is opened after the submission is sent

    so if you are on the form before it is submitted it acts as though there is still spots available which ends up over selling

    so i need another check while to be made, while the form is being submitted on all user ticket purchases for each child 

    so if a user signs only one child up it will only check the first child ticket purchases and make sure all spots are available

    but if a user sign two children up ( up to 4 ) it will check all childs ticket purchases and make sure they are spots available for all , if not it mist throw some error
