For the past hour, i’ve been trying to figure out my issue here:

- ServerScriptService.MainGame:129: attempt to concatenate string with nil

		for _,v in pairs(workspace.Map:GetChildren()) do
			for _,x in pairs(v:GetChildren()) do
				if x.Name == "Prisoner" then
					--if v.Prisoner.Value ~= nil then
					x.Value = nil
					print('Set Prisoner in '.. v.Name .." to nil".. x.Value) -- line 129
					--end
				end
			end
		end

Firstly, it would set only the first prisoner to nil as well without printing anything before the error as it should’ve as well, the 2 pictures above show an example…

I’m confused. You set x.Value to nil. Then you attempt to concentate x.Value, which is nil.

Try putting x.Value = nil after the print.

You cannot concentate nothing with a string…

I was sure you could print nil values for some reason…

Moving the print a line downwards gives me a new error:
attempt to concatenate string with Instance

:upside_down_face:

I realize since it’s an object value I may need to print x.Value.Name…

Yeah…

That is because you are using a ObjectValue, I guess you would want to see the name of the object before putting it to nil, so you’d say x.Value.Name.

These small things I break my sweat on, and also simple… Atleast this is why the dev forum community exists :slight_smile:
