I hate feeling needy and posting on this board like three times a week but I guess it's a good thing this board exists other-wise my programming problems wouldn't get solved

I'm using this code to calculate the point in 3-Space for my camera to look at. It pretty much takes the angle of the camera and the location of the camera and the distance of sight and calculates a new point(LookAt point).
Though there's some minor problems with it for what I am trying to do. such as if I rotate the Y-Axis the angle in which I am looking up at then changes. When I want it to stay at the same "pitch".
Is there a Z-Rotation for the camera? Is this not the series of equations I should be using? Is there a better way to do this?
My main problem is having my shooting script work with my camera. So I use that same method to shoot as well.
Thanks for reading, if you don't understand the problem I can post, you-tube video, a diagram a better explanation, and/or code. Just lemme know
