Trailing stop that follows a moving average?

What's wrong with this EA? I want the stop loss to follow the moving average. So if the stop loss of the order is less than the moving average the stop loss should be modified. What have I done wrong?

Edit: I can see that I forgot to attach the EA. Here it is.

Used it today...worked perfectly

Thanks. I would still like to know what I have done wrong in my code.
