I’m trying to make a variable that changes when a MC is on a certain frame. I tried to trace the variable both from the mc and the main timeline, however only the mc game me the correct value and the main timeline returned undefined. Is there any way I can make a variably inside of a MC that I can use from the main timeline?

you can define a global variable in your main timeline, by using:

[AS]\_global.myVar = value;[/AS]
