The script looks nice but I was unable to get it to actually work. Tech Support seems to think it's beacuse I have my production server and testing server as one physical server or I'm setting it up wrong in Dreamweaver 5.5. Both maybe true, I don't know.
But since I have 132 sites on the server and am connecting via php to 115 mySQL databases for everything from ecommerce to dental chart audit system all written in PHP I hesitate to change my server configuration for a calendar script.
dmxZone still creates some great Dreamweaver extension in my opinion, but I think this one may need a little more attention or a wider lattitude in its connection criteria.
