attempt to index a number value? help [FIxed]

I was making a script and on line 6 it all ways gives the error attempt to index a number value

local PathfindingService = game:GetService("PathfindingService")
local char = script.Parent
local Humanoid = char.Humanoid
while true do
    local path = PathfindingService:CreatePath()
    path:ComputeAsync(char.HumanoidRootPart.Position, Vector3.new(char.PrimaryPart.Position.X + math.random(-10,10),char.PrimaryPart.Position.Y + math.random(-10,10),char.PrimaryPart.Position.X + math.random(-10,10).Z)) -- the errors here
    path.Blocked:Connect(function()
        path:ComputeAsync(char.HumanoidRootPart.Position, Vector3.new(char.PrimaryPart.Position.X + math.random(-10,10),char.PrimaryPart.Position.Y + math.random(-10,10),char.PrimaryPart.Position.X + math.random(-10,10).Z))
    end)
    local waypoints = path:GetWaypoints()
    for _, waypoint in pairs(waypoints) do
        char:MoveTo(waypoint.Position)
        Humanoid.MoveToFinished:Wait()
    end
    wait(1)
end
