Thank you for your reply Eric.

Your recommendation worked!

Regarding the PHP code, I am reading a file that contains the capacity of several event venues. Based on the capacity and the number of registrants already signed up, I want to update the HTML to reflect the number of slots currently available. Then, when the number of available slots reaches 0, the registrant will be informed that they will be placed on a wait list.

I appear to have the PHP code working now! It isn't the prettiest code, I'm sure, but at least I've been able to prototype my web page and verify that I can do what I'd intended.
