Center Aligning Grid of Iterators.

So I decided to take a step back in TP to focus on simpler maths. But yet again, I am stuck.

I think this is a much simpler problem, but I've been stuck all day. I'm trying to take this grid I made with iterators and I am trying to make it always be centered as I scale up the particles in the X and Y axis. The thing is though that I want it to be centered around it's local axis because from what you see in the screenshot, it will be attached to a helper.

I tried using standard math of (x1 + x2)/2 and (y1 + y2)/2 and then plugging those values into a position Op to get the center point of the X and Y but it doesn't seem to be working. I understand that the Iterator will produce particles on the +/- side of the grid.

I also tried doing an offset but I would have to manually change it each time. I was trying to take the Vector's X and Y values and then multiply them (x1 * x2) and (y1 * y2) then get that result and use it as the center, but I am obviously doing something wrong.
