Help Error- 18 SOLVED thank you ;D

[Kooij]

Everytime I try and run my game, it starts up, shows the background then crashes with a message popping up saying an internal error has occurred. Engine 3.6.1.23

Error: RunScriptFunction:error - 18()trying to run 'room_Firstload" (room 1)

It only does this after I try and make a walkable area, and even if I delete whatever I did with the walkable part it still shows the message.

This means that you have a "room_FirstLoad" name added to room events, but no such function in script.
