unkown subwindow number -1 for object create function error

1mathboy1 2013.08.31 14:27
I'm using an indicator called 10.2 TMA slope, and although it compiles without errors, and even works in an EA, when I backtest my EA, a whole bunch of error messages pop up in the journal saying, \ 10_2 TMA slope v1_4B 4_30 for EA EURUSD,H4: unknown subwindow number -1 for ObjectCreate function. What is wrong with this indicator? I attached the code for the indicator.
