After installing Visual Studio and VisualMicro yesterday, I tried a simple sketch with a structure that I use for testing. Received the following debug errors. Any suggestions?

Compiling 'Structure_test' for 'Arduino Uno'
Structure_test.ino:6:1: error: 'RGB' does not name a type
:RGB getBlue();
:^
Structure_test.ino:7:1: error: 'RGB' does not name a type
:RGB printcolor (struct RGB m_rgb);
:^
Error compiling

// example about structures

struct RGB {
  int r;
  int g;
  int b;
} rgb, *pRGB;            //can create a struct or pointer to a struct

RGB printcolor (struct RGB m_rgb);            //MUST declare or get an undefined function error
RGB getBlue();

void setup(void){

//can fill struct members with data
  rgb.r = 3;
  rgb.g = 19;
  rgb.b = 255;

//can make a pointer to the struct
     RGB *p2RGB = & rgb;

//can assign a value through a pointer with the right arrow
     p2RGB -> r = 255;

//*pRGB is a pointer to a ITS OWN struct that was created at the top
  pRGB -> b = 12;
  printcolor (rgb);
}

//can declare structs in functions
RGB getBlue() {
     RGB color = { 0 , 0 , 255 };
     return color;
}

//can pass structs
//can return structs
RGB printcolor (struct RGB m_rgb){            //'struct' is optional but MUST match the above declaration
  m_rgb.r = 0;
  return m_rgb;
}

void loop(void){

}

This latest build solved the problem. The debugger is well worth the cost of this tool.
Thanks
