Square brackets are giving me a nil value?
I am trying to get my script to find a random value within another folder but on like 16 where I use square brackets, it says that I attempted to index nil ([box]) with 'Q'.
01 | local numbersentered = {} |
02 |
03 | script.Parent.BackgroundFrame.QuestionNumber.Changed:Connect(function() |
04 |
05 | local box = math.random(1,20) |
06 | print(box) |
07 | table.insert(numbersentered, box) |
08 |
09 | for i,v in pairs(numbersentered)do |
10 | if box == v then |
11 | local box = math.random(1,20) |
12 | print(box) |
13 | table.insert(numbersentered, box) |
14 |
15 | else |
View all 24 lines...
Any help is wonderful!

Questions is a folder, 'Q' is the name of the string values inside the folder. It goes from Q1 to Q20. GoingToAnnoyYou 2 — 4y

ANSWER: So according to your error, it doesn't seem to have to do with box. Your error (translated) means that :FindFirstChild("Questions") is nil.
Note: I can't help you further until I see your hierarchy and what this
Questionsobject is that you are looking for.

Questions is a folder which has a load of string values in it called "Q1" for example. It goes from Q1 to Q20. I am trying to get their values by calculating a random value, concatenating them and then bringing back the value of the string value into the script. GoingToAnnoyYou 2 — 4y

Separate your references out. Instead of make a long line, reference each thing in a variable, and then when you get to `Q` you will see what the real problem is. Roger111 347 — 4y
