The name "instance" does not exist in the current context

[zenfreak]

I'm trying to create a custom function and I'm getting The name "instance" does not exist in the current context when I try to use instance.ActiveTab.MouseMove. How can I use the instance from ActionGroup1 without defining a new one?

add an argument:
public static void myCustomFuction(Instance instance ,int var1,int var2)
{
..........
}
