I got this in the output of my game. What does it mean?

Workspace.main:19: attempt to concatenate global 'point' (a nil value)

That's what I found in output of my game.

It's in Lighting with a map. I got this from my minigame script. When you touch the finish button, this comes up in Output and the whole script breaks.

It means that you tried to combine whatever "point" is with a string, but it didn't work because the script can't locate what "point" is. Make sure that you have:

A) The correct path to "point"

B) "point" exists

C) If the parent of "point" changes, make sure the script notices that and does whatever is needed

Hope this helped!

That "point" is a nil value in other words point is not a valid member of workspace.
