i am trying to dupe a object but it is not working

local bullet = script.Parent.bullet
local dupes_of_bullet = bullet.bullets.Value
local turret_assaigned = bullet.turret_assaigned.Value
local bullet_clone = bullet:Clone()
local bullets_existing = bullet.bullets_existing.Value
local next_pos = bullet.next_position.Value

dupes_of_bullet = math.random(0, 10)

if dupes_of_bullet == 0 then
    warn("did not show bullet cuz dupe count = 0")
end

if dupes_of_bullet == 1 then
    bullet.Parent = turret_assaigned
end

if dupes_of_bullet >= 2 then
    repeat
        next_pos = next_pos - 1
        bullets_existing = bullets_existing + 1
        bullet_clone.Parent = turret_assaigned
        bullet_clone.Position = next_pos
    until bullets_existing == dupes_of_bullet
end

p.s the object i want to dupe is in server script storage

You can't subtract a number from a non-number value.

If you want to decrease a value from a Vector3 value, there are two ways that I would suggest:

Option 1:

local Result = next_pos - Vector3.new(1,0,0)

That will subtract 1 from next_pos's X value.

Option 2:

local Result = Vector3.new(next_pos.X - 1, next_pos.Y, next_pos.Z)

That will also subtract 1 from next_pos's X value.

If you want to subtract from next_pos's Y or Z value, you would adjust the code accordingly.
