Just declare your variables outside of the functions ;)

 public class SomeClass : MonoBehaviour
 {
   string someStringValue = "state1";
 
   void Update()
   {
     MethodNumber1();
   }
 
   void MethodNumber1()
   {
     if(someStringValue == "state1")
       someStringValue = "state2";
 
     MethodNumber2();
   }
 
   void MethodNumber2()
   {
     if (someStringValue == "state2")
       someStringValue = "state1";
   }
 }

Thank you for your answer. I already do this, i always declare my varialbe outsite the function but the things was that when i use a variable in FunctionA from FunctionB in function A the variable was always equal to 0 and in FunctionB it always change ( i know it becaus i use Debug.Log($$anonymous$$yVariable) to see if it works ) :/ Or maybe i just did something wrong in my code but i agree with you @Graphics_Dev this should world but in my case it didn't Have a good day

This might be very easy to solve if we saw your code... what type is the variable you are trying to change? If its a value type and you pass it in as a function parameter, then change the parameter in the function, the original value doesn't change. There are mamy Q's and A's about that here
