Checking a value in a part against a table?
What I'm trying to do is make a card access door, which when you touch your card against the scanner, it checks a value inside the card and if it is in "access" it unlocks a door.
local access = {
001,
}
script.Parent.Touched:connect(function(part)
if part.Parent:FindFirstChild("CardNumber") ~= nil then
if access[part.Parent.CardNumber.Value] then
local door = script.Parent.Parent.Parent.Door:GetChildren()
script.Parent.Parent.Card.Transparency = 0
script.Parent.Parent.Card.DecalA.Transparency = 0
script.Parent.Parent.Card.Decal.Transparency = 0
for i,v in pairs(door) do
v.CanCollide = false
end
wait(3)
script.Parent.Parent.Card.Transparency = 1
script.Parent.Parent.Card.DecalA.Transparency = 1
script.Parent.Parent.Card.Decal.Transparency = 1
for i,v in pairs(door) do
v.CanCollide = true
end
end
end
end)
There are no errors nor output.

The issue with how you have it set up is that you want to check if a table contains something else. Lua doesn't have an inherent way to do that, but what you can do instead is test to see if the key matches to a value.
Consider a table where you have your card numbers as keys instead:
allow = {
[002] = true;
[003] = true;
[005] = true;
[007] = true;
[011] = true;
[013] = true;
}
In this case, you can check if your card is allowed by doing what you're already doing, because it will either resolve to true or nil.
You must make sure that you're using the same type of value for your key. If the value you're trying to check for is a string, make sure that the keys are strings. Lua equality means that different datatypes are different.
