hi im ctg i got issule on table
im making matchmaking system but i got werid thing
when warn the table it return table
but when warn everything inside table it said the table is string

for i, v in pairs(GlobalMatchmaking) do
	warn(v) -- this warn table
	table.foreach(v, warn) -- this return error
	if #GlobalMatchmaking[i] + #GlobalMatchmaking[i] == 4 then	
		table.remove(GlobalMatchmaking[i], table.find(GlobalMatchmaking, i))
		--replicateStorage.MatchmakingClient:FireClient(v, "Matched", convertToHMS(times))	
		break
	end
end

error: invalid argument #1 to ‘foreach’ (table expected, got string)

Theres a value inside GlobalMatchmaking table which is a string instead of a table.
You are iterating a table and each entry contains supposedly a table, if any of those entries its not a table you will get that error, like this:

local Tab = {}
Tab["a"] = {"stuff"}
Tab["b"] = {"stuff2"}
Tab["c"] = "the string" -- issue

for i, v in pairs(Tab) do
	warn(v) -- this warn table
	table.foreach(v, print) -- this return error
end

You could patch it by checking if its a table before to do any table functions:

local Tab = {}
Tab["a"] = {"table1"}
Tab["b"] = {"table2"}
Tab["c"] = "a hidden string"
Tab["d"] = 3

for i, v in pairs(Tab) do
	if typeof(v) == "table" then
		table.foreach(v, print) -- this is a table
	elseif typeof(v) == "string" then
		warn("string:", v)
	else
		warn("what else?", typeof(v), v)
	end
end
