QUESTION QUESTION QUESTION

Alright, so... My script is erroring, and in the error box it's saying:

What is the error? (Added because I need to have a question mark)

1--[[
21x..3
320:03:55.332 - ServerScriptService.Main:28: attempt to concatenate local 'g' (a nil value)

Note, the script I will provide is NOT the entire script, but will be all that is needed...

01function getnextpos(Table)
02    local num = #Table
03    local toreturn = num+1
04    return(toreturn)
05end

07function a(z,selections)
08        local x = math.random(1,#z)
09        print("1x.."..x)
10        for index,returned in ipairs(selections) do
11            print(x)
12            if x == returned then
13                local y = a()
14                print("y.."..y)
15                return y
16            end
17            print("x.."..x)
18            return x
19        end
20end

22function selectrandom(location,count)
23    local z = location:GetChildren()
24    local selections = {}
25    for i = 1,count do
26        local val
27        local g = a(z,selections)
28        print("g = "..g)
29        table.insert(selections,getnextpos(selections),g)
30    end
31    return(selections)
32end

The issue, as I understand it, is NOT with my table, but with my returned variables, and functions I tried using a local function, but since it did not work, tried to move it out to a normal function, which also did not work. DO not worry about shortening any code you give me, as I can do that myself.

How should I fix this error?????? (Added because I "Need to have a question mark".)

Thanks, Taryo. ;)
