gluPickMatrix problems

So, I have the code (which I sort of combined from different websites since none of their code actually worked >.<):

    
    glInitNames();								// Initializes The Name Stack
	glPushName(1);								// Push 0 (At Least One Entry) Onto The Stack	
    mainMenu->draw();								// Render The Targets To The Selection Buffer
	glPopName();
	
    GLint viewport[4];
	
	GLuint	buffer[512];	
	glSelectBuffer(512,buffer);
	glRenderMode(GL_SELECT);

	glMatrixMode(GL_PROJECTION);
	glPushMatrix();
	glLoadIdentity();

	glGetIntegerv(GL_VIEWPORT,viewport);
	gluPickMatrix(mouseX,viewport[3]-mouseY,
			5,5,viewport);
	gluPerspective(45.0f, (GLfloat) (viewport[2]-viewport[0])/(GLfloat) (viewport[3]-viewport[1]), 0.1f, 100.0f);
	glMatrixMode(GL_MODELVIEW);
	glInitNames();
	
	// restoring the original projection matrix
	glMatrixMode(GL_PROJECTION);
	glPopMatrix();
	glMatrixMode(GL_MODELVIEW);
	glFlush();

	glMatrixMode(GL_MODELVIEW);						// Select The Modelview Matrix
	int hits=glRenderMode(GL_RENDER);						// Switch To Render Mode, Find Out How Many
	
	if (hits != 0)								// If There Were More Than 0 Hits
	{
		int	choose = buffer[3];					// Make Our Selection The First Object
		int	depth = buffer[1];					// Store How Far Away It Is
		
		for (int loop = 1; loop < hits; loop++)				// Loop Through All The Detected Hits
		{
			// If This Object Is Closer To Us Than The One We Have Selected
			if (buffer[loop*4+1] < GLuint(depth))
			{
				choose = buffer[loop*4+3];			// Select The Closer Object
				depth = buffer[loop*4+1];			// Store How Far Away It Is
			}       
		}
		
    mainMenu->moveY(0.5);
        
    }

The problem is that the 'hits' variable is always 0, apparently, because my mainMenu object is never moved at all :Here is the mainMenu->draw function:

     for(int i=0;i<=numberOfObjects;i++)
     {
     objects.draw();
     }

and the object 'objects' drawing function:

     glBindTexture(GL_TEXTURE_2D, theTexture.GetID());
     for(int i=0;i<=((((numberOfVertices+1)/3)/(numberOfVerticesInAShape+1))-1);i++)
     {
     shapes.draw();
     }

and the object 'shapes' drawing function:

for(int i=0; i<=numberOfVerticesInTheShape; i++)
{
vertices.setZ(vertices.getZ() + addZ);
}

I know that the drawing functions are working fine because when I draw them to the screen, it displays the objects that it is supposed to. Hmmm...I don't know how useful the drawing functions were, but....*shrugs* Any help is appreciated :) -wyrmmage
