Script not setting a tostring(index) into a (value) of a different table?

I have no idea why it won't do it.

getCommands = function() -- WIP
		local result
		local functions
		functions = {}
		print(functions)
		local toChar = CVExtra.toCharList
		local toString = CVExtra.charlistToString
		local function searchTable(tab,nam)
			local parent = ""
			for i,v in pairs(tab) do
				if tab==nil or nam==nil or tostring(tab)==CVExtra then
					parent=""
				else
					local nam2 = toChar(nam)
					nam = toString(nam2)
					print(nam)
					print(nam2)
					parent=""..nam
				end
				if typeof(v)=="function" then
					print("function")
					local funcr = ""..tostring(i)
					local func = toChar(funcr)
					funcr = toString(func)
					func = funcr
					if parent=="" then
						
					else
						func = parent.."."..funcr
					end
					table.insert(functions,func)
				elseif typeof(v)=="table" then
					print("table")
					searchTable(v,tostring(i))
				end
			end
			return tab
		end
		result = searchTable(CVExtra)
		return result
	end

Since concatenation wasn't working, I used one of my scripts that changes the individual letters of a string (toChar) to a table of individual letters. Then has it converted back into a string with toString (custom function)

I've done numerous prints to test and figure out where it goes wrong, but I think it's Roblox. Because somehow even though I set the value of another table to a string, turn it into a table then back into a string and concatenate it, it still puts it as an index for another table, a dictionary.

Of course, the only other alternate solution I could think of is to get the names of the things I want printed, into a table for the script to print, but I want it to get the "commands" I have from my module I am making.

(Edit)

For anyone wondering, "CVExtra" is a table with functions and other tables in it.
