Transform position of child object and look at it

Hello!

I hope the headline is not too confusing. At the moment I transform the position of a blank gameobject to use it for a LokkAt rotation. The problem is, that I do something wrong with the child object. I will simply post pictures of the hierachy.

I would like to transform the LookAtRight and LookAtLeft objects with own x and y coordinates and let the shoulders look at it with LookAt. But they use them in another way I guess? If I send the x position as 140 it has a completly different position in Unity. I am very confused about this.

And here is the code where I split the strings and get the coordinates and Update the positions in Unity:
