problems with tables

Hi
My problem is the following:

In one function i give an table with variable keys a value.

Code:

function test(self, ...)
    ID=2
    Player=Bob
    level=80

    data[ID][Player][level] = "something"
    test2(self,...)
end

Now if i want to use this table in another function like this:

Code:

test2(self,...)
    text = data.2.Bob.80
end

it returns nil everytime. but in my savedvariables this table has its value.
Can someone please explain me what i am doing wrong

first you have to make sure that each subtable is created before using it

Code:

data[ID] = data[ID] or {}
data[ID][Player] = data[ID][Player] or {}
data[ID][Player][level] = data[ID][Player][level] or {}

also you can not use the . table notation for numbers or strings that start with numbers

as such when you want to reference it again you need to use:

Code:

data[2].Bob[80]

or

data[2]["Bob"][80]

Also you seam to have a somewhat inefficient database layout

why not do something like this

Code:

data[ID] = {
     ["name"] =  "Bob",
     ["level"] = 80,
     ["text"] = something,
}

this way you only create one table per ID (saves memory and will probably make it easier to look through your SV file while also making it a little bit faster to load)
