How do I make an IntValue that tells me how many players are on another place?

I've got a gui that when I press a button, it teleports me to another place that's in the game. How do I make an IntValue that tells me how many players are playing that place? Something that looks like this: Players: 10

You'd want to use HttpService with this. You could simply parse the HTML of the game's page to see how many players are in it. You'd need to use a proxy for this since you can't send HttpService requests directly to Roblox.

Using DataStoreService for this would be a hack, but would potentially be technically possible.
