In order to allow us to diagnose and fix the problem you have just encountered.
Please include as much information about the problem as you can.
It is much easier for use to fix the problem if we can reproduce it. So if you can consistently make the error occur tell us how you do it, and include all the files that are needed (including any imported or included ones).
