Hello! When i type

local rank = fromJSON(f.ranks)

This system fractions and is 85 lines, not the entire required. Paste the most important passage:

  
local f = exports.DB2:pobierzWyniki("SELECT * FROM `prs_frakcje` WHERE `id` = "..getElementData(source, "fid")) 
                local u = exports.DB2:pobierzWyniki("SELECT * FROM `prs_frakcje_players` WHERE `uid` = "..getElementData(plr, "auth:id")) 
  
                setElementData(plr, "f.name", f.nazwa) 
                setElementData(plr, "f.id", f.id) 
local rank = fromJSON(f.ranks) 
outputChatBox(#rank) -- !!!! prints 0

try sth like this

    local check = exports.DB2:pobierzWyniki("SELECT * FROM `prs_frakcje` WHERE `id` = "..getElementData(source, "fid")) 
    if type(check) ~= "table" or #check ~= 0 or check then 
    local rank = fromJSON(check[1]["ranks"]) 
    -- Your code 
end

Thank you for your help, but I decided to make this system more robust so that I will not be able to use this solution.
