If you look at the error message it is telling you that it found an undefined variable "handler" in module rsappt_pro14_front_desk.php on line 34. Since you don't have a reference to "handler" on line 34 in the module that you have posted, I suspect that this isn't module rsappt_pro14_front_desk.php. There is a reference to $handler on line 10 in this module. You could post some or all of the code (including line 34) from module rsappt_pro14_front_desk.php. The bottom line is probably that $handler wasn't defined somewhere and that might be the result of some other error. It might be that it is supposed to be defined in one of the two modules included prior to line 10 in this module. It may also be that something wasn't defined (correctly) in a config module and that has rippled through a number of modules and ended up creating this error. You will probably need to find out where $handler is supposed to be defined before you can make any sense of this.

Try replacing the problem line with the following:

$session = &JSession::getInstance(NULL, $options);

When E_Notice is disabled that is the equivalent to what is set. To problem with your code is that $handler was never set a value. So I have put into getInstance an empty variables default value for you. :)
