Yes, that's the ticket. I wondered about the alert(the_url); line. It used to be commented out. On the other issue, not having the "comments" row in my database table, yes, I didn't have that in there. I moved the whole thing to a different server and forgot to add it back in. Now, everything seems to be working. I just added a date with comment, and when I looked at it in phpmyadmin, it's all there, including the comment.
It might still be a little unwieldy for client use. You have to enter the comment before selecting the date. If you do it the other way around, the comment isn't sent to the database. That sounds like a lot more code. Hum, maybe this will be for yet another day. (I realize this wasn't meant to do this comment stuff. Perhaps, when I learn more, I'll take a stab at it, myself.)
Anyhow, I'm going to try to use it as is. My plan is to use an if exists to display the dates and comments in a table beneath the calendar on the front end. Something like that. I'll have to think about it.
Thanks again for all your help. You're the best.
