Hi ! I have written a simple function in a class like this :

class myClass
{

public:
   /* other members */

   double xyz(unsigned int id, unsigned int valIndex, unsigned int tupleIndex) const
   {
      return id * valIndex * tupleIndex;
   }

   bool createScriptingEngine
   {
      /* must-be-done stuff */
      	ScriptingEngine->RegisterGlobalFunction(
	   "double xyz(uint, uint, uint)",
	   asMETHOD(myClass, xyz),
           asCALL_THISCALL_ASGLOBAL,
           this);
      /* other stuff */
   }

   /* other members */

};

After I created an instance of myClass and called createScriptingEngine function. Then when i tried to run the following script :

class ng
{
   /* other members */
   private uint index;
   private uint ngId;	/* id of numgen */
   int getIntTupleElement(uint i)
   {
       return xyz(ngId, index, i);
   }
   /* other members */
}

/* other things */

And I got the error : No matching signatures to 'xyz(uint&, uint&, uint) . So the questions are : Why do I get this error ? AND How can i fix it ???

I solved it. Just a simple spelling mistake.
