This script has multiple errors not in output and I don't know why?

This code is supposed to make a brick spawn every 10 seconds on a brick spawner (which it is parented under), with a slight chance of being a golden brick, and the brick is given an IntValue. Past bricks are supposed to be deleted.

The two problems I faced:

Multiple bricks spawn at a time

Past bricks are not deleted

Code:

while wait(10) do
    for i,v in pairs(script.Parent:GetChildren())do
        if v.Name == "Brick" then
            v:Destroy()
        else
            bval = math.random(1,100)
            if bval <= 99 then
                brick = Instance.new("Part", script.Parent)
                brick.Position = script.Parent.Position
                brick.Size = Vector3.new(2,0.5,1)
                brickval = Instance.new("IntValue")
                brickval.Value = 1
            elseif bval == 100 then
                brick = Instance.new("Part", script.Parent)
                brick.Position = script.Parent.Position
                brick.Size = Vector3.new(2,0.5,1)
                brick.BrickColor = BrickColor.new("New Yeller")
                sparkles = Instance.new("Sparkles", brick)
                brickval = Instance.new("IntValue")
                brickval.Value = 25
            end

        end
    end
end

I don't understand the cleanup process. You're destroying objects with the name of "Brick", yet objects you create are not named such. Goulstem 8144 — 7y

Well, that makes me an idiot lol. But I still don't get why multiple bricks spawn at a time... obcdino 113 — 7y

Okay, now I'm actually very stupid, both problems were fixed, thanks. obcdino 113 — 7y

(I see you already figured it out, but) the way I'd do it is:

local brick, brickval, bval
while wait(10) do
    if brick then brick:Destroy() end -- Destroy the old part (if any)
    -- Make a new one
    brick = Instance.new("Part")
    brick.Size = Vector3.new(2,0.5,1)
    brick.Position = script.Parent.Position
    brickval = Instance.new("IntValue")
    bval = math.random(1, 100)
    if bval <= 99 then -- Normal
        brickval.Value = 1
    else -- Golden
        brick.BrickColor = BrickColor.new("New Yeller")
        brickval.Value = 25
        local sparkles = Instance.new("Sparkles")
        sparkles.Parent = brick
    end
    brickval.Parent = brick
    brick.Parent = script.Parent
end

Do note that Instance.new(part, parent) is deprecated - you're supposed to do .Parent after you've changed the other properties (especially Size and Position, which cause a bit of unnecessary lag if the part is already in the Workspace). This isn't a concern when you're only making 1 part every 10 seconds, but it's good practice nonetheless.

I changed the structure a bit so that the common code is outside the if block; you can see exactly what makes a brick normal/golden.
