get pivot of editable poly selection

nvm. it works now. :)

for example, I created a cube (100x100x100) at the origin. The verts were (50 50 50),(-50 50 50), (50 -50 50),...

I did their average and got [0,12.5,12.5]...

My first question, is an averaging of all the verts the operation on need, and if so, what am I doing wrong in the source?

(
	local theObject
	local theVerts
	local avgX
	local avgY
	local avgZ
	local myVector
	local temp

	theObject = selection[1]
	theVerts = polyop.getVertSelection theObject
	theVerts = theVerts as array
	
	for i = 1 to (theVerts.count - 1) do
	(
		avgX = (polyOp.getVert theObject theVerts[i]).x + (polyOp.getVert theObject theVerts[i+1]).x
		avgY = (polyOp.getVert theObject theVerts[i]).y + (polyOp.getVert theObject theVerts[i+1]).y
		avgZ = (polyOp.getVert theObject theVerts[i]).z + (polyOp.getVert theObject theVerts[i+1]).z
	)
	
	avgX = avgX / theVerts.count
	avgY = avgY / theVerts.count
	avgZ = avgZ / theVerts.count
	
	myVector=[avgX, avgY, avgZ]
	
	print myVector
)
