My airdrops spawn, but they are in the same position as in the first place. Any help?

I have an airdrop script. I am currently making the part when it spawns automatically.

I have the airdrop model in ReplicatedStorage. I clone the part in the script, and set the position randomly.

The part spawns in the Workspace, but its position isn't set to a random position. The position is the exact position that the model is at.

Here is the Server Script:

local radcash = math.random(1000, 5000)

local part = game.ReplicatedStorage.DropItem.drop

local radposx = (math.random(100.2, 320.8))

local radposz = (math.random(1.3334, 172.2))

while true do

wait(60)

local clonedDrop = part:Clone()

if clonedDrop then

local dropmodel = Instance.new("Model",workspace.Drops)

dropmodel.Name = "AirDrop"

clonedDrop.Parent = dropmodel

local xvalue = (clonedDrop.Position.X)

if xvalue then

local zvalue = (clonedDrop.Position.Z)

if yvalue then

xvalue = Vector3.new(radposx)

yvalue = Vector3.new(radposz)

clonedDrop.Position.Y = Vector3.new(2.29)

end

end

end

end

Any help?
