Move n-Objects in a row to a point "B", looking at it

Hi, I have already figured out how to place a number of n cubes, all looking at the same point B. But the issue here is, that they don't spawn in a row, which is also looking at point B (row-direction to B). The Position of Point B is variable before runtime. I already thank you in advance!
