How do I get -> to work?

Hey,
I have a struct .h file, another h file and a .cpp file with my main method. I am trying to make a list using the data type I created in my struct file, but it is not recognizing -> and keeps throwing error:

OrthogonalLinkedSparseMatrix.h:46: error: base operand of ‘->’ has non-pointer type ‘OrthogonalNode’

where OrthogonalLinkedSparseMatrix.h is my implementation header file and OrthogonalNode is my struct class.

OrthLinkedSparseMatrix has code:

	}
	
	 OrthogonalNode rowList;
	 OrthogonalNode colList;
	
	//void transpose(OrthogonalLinkedSparseMatrix &b);
	//void add(OrthogonalLinkedSparseMatrix &b, OrthogonalLinkedSparseMatrix &c); 

private:
	int rows;    // number of rows in matrix
	int cols;		 // number of columns in matrix
	int TotValues;


and the struct program has

#ifndef OrthogonalNode_
#define OrthogonalNode_
//#include "OrthHeaderNode.h"

//no template class. Can only use integers
struct OrthogonalNode
{
	// data members
	 int value;
	 int row;
	 int col;
	 OrthogonalNode *right;
	 OrthogonalNode *down;
};
#endif

Why won't it let me use -> ???
Thank you

Maybe because you commented it out - nah only joking - is it a pointer? the -> dereference a pointer it would be kind of like #

(*)newnode.row = r;

new node has to be initialized as a pointer to be able to use the -> tool.
