I would like to know how I can make a bracket set of [ ] in a string, for example

a string’s value to be [“123”,“123”]

see how there’s the [ brackets surrounding them.

The Problem is that I don’t know what the correct coding is in order to achieve this effect, i’ve tried setting the string value but it errors

The ' is your friend. : )

YourValue.Value = '["123","123"]'

If you don’t know the exact contents of your array beforehand, you might be interested in encoding it as json (which turns it into a string) and decoding it when you want to read it (which turns it back into an array):

local http = game:GetService("HttpService")

local myArray = { "123", "123" }

-- when you want to save it:

local asAString = http:EncodeJson(myArray)

TraitKeeper.Value = asAString

-- later when you want to read it:

local backAsAnArray = http:DecodeJson(TraitKeeper.Value)

You can use [[ or ':

value.Value = [["123","123"]]

Thank you, I have another question

How do I insert strings into the brackets?

If I have a string

myValue.Value = ‘[ ]’

how do I insert “123” , “123” into it so it becomes

print(myValue.Value) --[“123”,“123”]

?
