Why is this not detecting that the player is not in range?

This is supposed to print something when the player is hovering over a certain item and within 10 studs and it definitely does print but it does not matter how far the player is for some reason.

local m = require(workspace:WaitForChild("Modules"):WaitForChild("MainModule"))
local RunService = game:GetService("RunService")
local player = game:GetService("Players").LocalPlayer
local char = workspace:WaitForChild(player.Name)
local Mouse = player:GetMouse()

RunService.RenderStepped:Connect(function()
    local target = Mouse.Target
    if target:FindFirstChild("CanHarvest") then
        if target:FindFirstChild("CanHarvest") then
            if char.UpperTorso.Position.X - target.Position.X > -10 or char.UpperTorso.Position.X - target.Position.X < 10 then
                if char.UpperTorso.Position.Z - target.Position.Z > -10 or char.UpperTorso.Position.Z - target.Position.Z < 10 then
                    print("ITS WORKING! (Maybe)")
                    m.overTarget = true                    
                end
            end
        else
            m.overTarget = false
        end
    else
        m.overTarget = false
    end
end)
