You can’t fully run the patch without these abstractions/externals, so we can’t really help much until they’re provided. Also there are so many cords going to these that it will be difficult to determine what’s happening. It’s rare that you need so many cords, there is almost certainly an easier way to do what you’re looking for. Maybe a bit more explanation of what you’re trying to accomplish will help.

also watch the Max window, I get this error when moving the node:

matrixctrl: lists must be of the form

check the matrixctrl help file for proper formatting to set cells.

If you want the X axis cells to react to the size, you need to determine the size first, then decide how many cells will react to a given size. You could then set the cells directly, using an appropriate starting point from left to right (I assume you want the position of the node to determine this). So half the size goes to the left of center, half goes to the right, with rounding as needed.
