this is where the error isthis is what I'm calling also there in different scriptsI've got a null reference exception when I try to call a void in another script pls help
In which line are you getting the null reference? Null reference exception means what you are trying to access something that has no reference, so it could be that you have no reference to your GameManager when calling the "nextLevel" method.
you probably wrote the scene name wrong. an other way to change scenes is with their index number which also makes it easier to go to the next level maybe take a look at that.
