Hi Oma,

There's a parse error in your code, you need to remove the extra '}'. I've split up your code so you can see where the error is.

Also you could alter your php.ini file, and change these values to:
error_reporting = E_ALL
display_errors = On

This will show you where the errors are. Although note that "display_errors = On" isn't recommended for production systems and should be Off.

If you prefer not to enable "display_errors" you could look for your web server's error log, as it should be in there too.

It shouldn't. I see you have a file named functions.php included into your file at the top. Look in that file for the checkSelection function and ensure that it is there. Maybe the casing is incorrect, as function and variable names are case sensitive.

Well, if you can, try and obtain a copy of functions.php from whomever gave you the code. Apparently there's a function you need and it's missing.

Also, a group of dynamic drop downs like that would be much easier to do with just Javascript that's generated by PHP. Something described in this thread.
