for loop telling me variable is a number value after using GetChildren()?
Yeah so I get the children of a GUI and then use a for loop to check the children yet its telling me it cant because its a number value? Since when does :GetChildren() return a number?
local but = script.Parent
local site = script.Web.Value
local ser = but.Parent.SerBar
local url = script.URL
but.MouseButton1Click:connect(function(plr)
local gui = but.Parent:FindFirstChild(site):GetChildren()
local all = but.Parent:GetChildren()
for v = 1 , #all do
if v.ClassName == "Folder" then
local gc = v:GetChildren()
for e = 1, #gc do
e.Visible = false
end
end
end
ser.Text = url.Value
for i = 1, #gui do
i.Visible = true
end
end)
This is the Error
Players.CrispyBrix.PlayerGui.SurfaceGui.WHITE.Home.Click:10: attempt to index local 'v' (a number value)
Any help is appreciated

First variable in for loop is always a number. Add ",v in pairs" or ",v in ipairs" to get the wanted value. Meltdown81 309 — 6y

This is not how you use a numerical loop to access an array. You are using the number in the loop as opposed to using the number to access the element in the array.
Example.
local tbl = {'a', 'b', 'c'}
for i=1, #tbl do
print(tbl[i])
end
You should have also read the error which explains the issue in your code as looping through tables is a basic part of programming.

Try this
local but = script.Parent
local site = script.Web.Value
local ser = but.Parent.SerBar
local url = script.URL
but.MouseButton1Click:connect(function(plr)
local gui = but.Parent:FindFirstChild(site):GetChildren()
local all = but.Parent:GetChildren()
for i,v in pairs(all) do
if v.ClassName == "Folder" then
local gc = v:GetChildren()
for u,f in pairs(gc) do
f.Visible = false
end
end
end
ser.Text = url.Value
for i,v in pairs(gui) do
v.Visible = true
end
end)
