When I use Mouse.Hit.p it keeps going towards my camera? (Any Fix?)

Try this version of the script. Just changed 2 lines that i noted.

local player = game.Players.LocalPlayer
local mouse = player:GetMouse()

mouse.KeyDown:connect(function(key)
    if key == "1" then
        --//Magnet Release\\--
        if script.Parent.Jutsu.Value == "SandManipulation" then
            local MoveableSand =  game.ReplicatedStorage.Test:Clone()
            MoveableSand.Parent = game.Workspace
            wait(0.1)
            mouse.Button1Down:connect(function()
                for i = 1, 1000 do
                    wait(0.01)
                     if mouse.Hit.Name ~= "MODELNAMEHERE" then  --Add this
                    MoveableSand.Position = mouse.Hit.p
                   end -- And this
                end
            end)
        end
