Hello, I tried to use table.Concat but it didn’t work and I didn’t get a value. When I print out the table it prints out but when I convert it to a string then it doesn’t work.
table and string printed:

code:

for i,v in pairs(inventory) do
		if i == slot then
			print(v)
			local str = table.concat(v)
			print(str)
			return str
		end
	end

I looked at that but I still don’t understand it

#4

You’re trying to concat a dictionary, that doesn’t work as it only works for tables, what are you trying to do exactly?

#5

Table.Concat is basically short for string.join()(Used in JavaScript or Java), which is used to join arguments in the table together into a string, sep is the seperator in which that’ll be used like table[iterator]..seperatorhere..table[iterator2]

#6

get the value of v and put it into a string so I can split the value etc

#7

Which value? The key, Apple, or the value of that key, 1? You can only get one or the other or both if you do it twice

#8

Im trying to get the key Apple How can I do this?

#9

I think something like this if each dictionary only has 1 key in it

for i,v in pairs(inventory) do
	if i == slot then
		print(v)
		local str
		for key, value in pairs(v) do
			str = key 
		end
		print(str)
		return str
	end
end
