Multi Heikin Ashi Smoothed in one indicator

Hi all,

I'm very new to MQL4 programming. Still learning and looking how to make some indicator for my own use. I face difficulty when creating multi Heikin Ashi Smoothed indicator.

 Below is my code for the indicator. After I compile, it can only see MAPeriod1 only. If I can MAPeriod1 style to LINE. then I can see MAPeriod2 only. Any possible way to make 3 MAPeriod to show in chart?

#property indicator_chart_window

#property indicator_buffers 13

#property indicator_color1 DarkViolet

#property indicator_color2 Aqua

#property indicator_color3 DarkViolet

#property indicator_color4 Aqua

#property indicator_color5 Gold

#property indicator_color6 DarkViolet

#property indicator_color7 Aqua

#property indicator_color8 DarkViolet

#property indicator_color9 Aqua

#property indicator_color10 DarkViolet

#property indicator_color11 Aqua

#property indicator_color12 DarkViolet

#property indicator_color13 Aqua

#property indicator_width1 1

#property indicator_width2 1

#property indicator_width3 4

#property indicator_width4 4

#property indicator_width5 1

#property indicator_width6 1

#property indicator_width7 1

#property indicator_width8 4

#property indicator_width9 4

#property indicator_width10 1

#property indicator_width11 1

#property indicator_width12 4

#property indicator_width13 4
