I really think you should try solving the error before putting in more code.
Just a guess - looks like the combo box is being assigned a value before data has been loaded into it.

There are two ways to handle this:
1) Put a try...catchblock around the code, and display your alert in the catch block.
2) Use the debugger to find out exactly what is generating the exception and fixing it, by checking before you cause the error. Since you have the debugger catching the exception, it should be obvious from your code what is causing this.

Myself, I would do option two: Exceptions should not be used as a normal part of processing: they are there to let us know when we have done something wrong, not the user!

Without a relevant code fragment, I cannot help you fix the actual problem throwing the exception...
