this just adds them up, so it doesn't work

crisp edge Feb 23, 2024, 7:06 PM

#

wym

#

adds them up

#

can you send the whole code

#

i dont understand ur messy code

unique solar Feb 23, 2024, 7:09 PM

#

oh sorry, it doesn't add them up but it actually gives this error got something mixed up my bad:

crisp edge Feb 23, 2024, 7:10 PM

#

ok so u got a string

#

full of numbers?

#

seperated in commas?

unique solar Feb 23, 2024, 7:10 PM

#

ye

crisp edge Feb 23, 2024, 7:11 PM

#

alr

#

wait

unique solar Feb 23, 2024, 7:11 PM

#

I have another thing that works, so it's aight if you don't know

#

until you figure something out I will return it to how it was

crisp edge Feb 23, 2024, 7:14 PM

#

"1, 1, 4, 9, 12, 8, 6, 9, 9"

#

this would be

#

1199?

unique solar Feb 23, 2024, 7:15 PM

#

no the duplicates would be shortened to just 1,9

crisp edge Feb 23, 2024, 7:15 PM

#

alr

unique solar Feb 23, 2024, 7:15 PM

#

but that works too I could just tweak it

crisp edge Feb 23, 2024, 7:17 PM

        end
    end
    if found >= 2 and not string.match(duplicateString, v) then
        duplicateString = duplicateString..v..","
    end
end
print(duplicateString)

here

#

lmk

#

if it woroks

unique solar Feb 23, 2024, 7:20 PM

#

doesn't work:

#

I can send a vid if you want

crisp edge Feb 23, 2024, 7:23 PM

nor doing anything w it?

unique solar Feb 23, 2024, 7:47 PM

it doesn't execute due to this error:

so you gotta fix it first

I could print somewhere else actually hold on

i just need debugging

unique solar Feb 23, 2024, 8:02 PM

well you got the script lol

change

crisp edge Feb 23, 2024, 8:05 PM

#

oh wait

#

wtf

#

im confused

#

how is ur textbox

#

supposed to look like

#

when u type in something

#

why are u doing subbing

unique solar Feb 23, 2024, 8:08 PM

#

because it's two textboxes that look like this:

{1,2,3,4} - {2,3,4}

therefore the string.sub("string", 1, -2) and string.sub("string",2,-1)

#

to handle the curly brackets yk

crisp edge Feb 23, 2024, 8:09 PM

#

unique solar ```lua local FullSet1to2to3 = string.sub(SetBox1.Text, 1, -2)..","..string.s...

did it print whats FullSet1to2to3

unique solar Feb 23, 2024, 8:09 PM

#

crisp edge did it print whats FullSet1to2to3

yes I already told you

unique solar Feb 23, 2024, 8:09 PM

#

unique solar oh now that I did that, FullSet1to2to3 when printed outputs: {1,2,3,4,1,3}

right here

crisp edge Feb 23, 2024, 8:09 PM

#

unique solar oh now that I did that, FullSet1to2to3 when printed outputs: {1,2,3,4,1,3}

why does it still have curly brackets

unique solar Feb 23, 2024, 8:10 PM

#

crisp edge why does it still have curly brackets

the string.sub() leaves certain brackets per string so it can result in a string that has {}

crisp edge Feb 23, 2024, 8:10 PM

#

cant u have

#

TextLabal TextBox TextLabel

#

and the textlabel

#

has text

#

of curly bracket?

unique solar Feb 23, 2024, 8:11 PM

#

yeah but then this happens:

{1,2,3,4}{2,3,4}

#

not ideal

crisp edge Feb 23, 2024, 8:11 PM

#

why tf

#

#

it prints right

#

but when u put

#

string in split

unique solar Feb 23, 2024, 8:11 PM

#

yeah

crisp edge Feb 23, 2024, 8:11 PM

it says its nil

give me code

why did you comment the current one

crisp edge Feb 23, 2024, 8:13 PM

to see if it works

with custom

cuz its not supposed to be nil

if it prints its a string

you want proof?

then why is ur ass here?

if u got working method

it works fine

thought you could provide me with an actually better method
