Question

I created a form with Single Choice fields, 4 days with times listed. But, I want the user to only be able to choose one time, and the time chosen to be unavailable for other users. How do I do this? I have 4 blocks of Single Choice fields in order for the summary page to give me each day in the final report. But, I need the user to be able to make a selection of any day and time and that apointment to no longer be available to future users when they log in. Plus, when the user clicks on the time, they are unable to change their mind and choose another time.

I'm afraid not.    It's not rocket science but you need to do some coding. 
You'll need to find a script (php) and save it to your local site folder.  Then reference the script in your form's action attribute like so.
     <form action="path/form-to-email-script.php" >
The input fields in your HTML form need to exactly match the script variables. 
I'm  assuming you're hosted on a Linux server which uses PHP code.  Linux servers are also case sensitive, so upper case names are not the same as lower case names.  It's usually best to use all lower case names in your form and script to avoid confusion.
