"Error #1009" Means you're trying to dereference something that is null.
If you get that error on a line like this:
foo.bar
or
foo['bar']
It means that foo itself is null, not that foo exists and doesn't contain a
"bar" field.
A tip: When you get this exception, try using the "Variables" window in the
debugger to help track down what it is that's giving you curry!
