I am trying to get a part to move with the players mouse but at the same time stay within the boundaries of the players base. To get the part to stay in the base I am getting the sides of the hitbox (the parts 'primary part') and the base. I then check if the right side of the hitbox is greater than the bases right side and if it is then set the x of hitbox's position to the right side of the base. I do that with all the other sides. What happens when the program runs is the part just stays in the left back corner and in my output I see 'left' and 'back'

		--[[
		x and z are by default the mouse x and z (this is not shown in this snippet)

        -- Get sides of hitbox
        local hSides = {
            right   = hitbox.Position.X + (hitbox.Size.X / 2);
            left    = hitbox.Position.X - (hitbox.Size.X / 2);
            forward = hitbox.Position.Z + (hitbox.Size.Z / 2);
            back    = hitbox.Position.Z - (hitbox.Size.Z / 2);
        }

        -- Get sides of base
        local bSides = {
            right   = base.Position.X + (base.Size.X / 2);
            left    = base.Position.X - (base.Size.X / 2);
            forward = base.Position.Z + (base.Size.Z / 2);
            back    = base.Position.Z - (base.Size.Z / 2);
        }

        if hSides.right > bSides.right then
            print("right")
            x = bSides.right
        elseif hSides.left < bSides.left then
            print("left")
            x = bSides.left 
        end

        if hSides.forward > bSides.forward then
            print("forward")
            z = bSides.forward
        elseif hSides.back < bSides.back then
            print("back")
            z = bSides.back
        end

        -- Set item position
        local newPos = Vector3.new(x, (base.Position.Y + (base.Size.Y / 2)) + (hitbox.Size.Y / 2), z)

        item:SetPrimaryPartCFrame(CFrame.new(newPos))
