I have installed this script.
I have also setup my own and one of the example DB and both do the same thing.

[www.ymcasydney.org.au]

when the page loads it looks like the script is working fine. However if i change the first drop down the second drop down either never loads or take forever to load up the next values.

Does anyone know why this is. Can anyone help me debug this.

Thanks in advance
Ilan
