glArrayElement is chucking access violation at me.

OpenGL OpenGL: Basic Coding

Hello forum,
I’m an absolute beginner and OpenGL is giving me issues with array element 0 of one of my (very simple) Vertex Arrays.
The relevant (or what i believe to be relevant) code is this:

void ground()
{
	//create the vertex array
	triple groundVertex[4] = {{45.0, 0.0, 45} , {45.0, 0.0, -45.0} ,{-45.0,0.0,-45} , {-45.0,0.0,45.0}
	};

	glVertexPointer(3,GL_FLOAT, 0, groundVertex);
	
	glBegin(GL_QUADS);
	glArrayElement(0);
	glArrayElement(1);
	glArrayElement(2);
	glArrayElement(3);
	glEnd();

}

When I compile it seems to throw this error at me.

“Unhandled exception at 0x692eada6 in wk7.exe: 0xC0000005: Access violation reading location 0x00000004.”

And when i break it seems to point to Array Element 0.
I cannot think of what it could be.

did u enable vertex arrays ? befrore specifying the vertex pointer ?
if no, put this line
glEnableClientState(GL_VERTEX_ARRAY);
before :
glVertexPointer(3,GL_FLOAT, 0, groundVertex);

Yes i did, in my initialize function. Does it need to be done elsewhere??

check ur call stack functions to see which function is throwing this exception
