{
  nameea == 0)
  {
    if(GlobalVariableGet(GLOBAL_NAME) != WindowHandle(Symbol(), Period())) 
    {
      nameea = -1;

there are some clear errors in the syntax of your code. The snippet you have sent here will not compile 

 
chukwudi joshua obiekwe: ,pls any assistance. 

  1. Do not post code that will not even compile. We assume you know the language.

  2. Post all relevant code.

    How can we know whether you used strict or not.

    Always use strict. Fixing the warnings will save you hours of debugging, but you must understand the differences.

  3. Where do you call onint?

  4. What is the purpose of nameea? It is unnecessary.

It's a typo error mean to type  void OnTick() not 
int onint()

Always the last initialized EA instance is allowed to run. Even if you change timeframe the EA init will set the handle of that chart.

but i just want to know what am doing wrong now,

#property strict

string GLOBAL_NAME = "myeaname";

int init()
{
  //...
  GlobalVariableSet(GLOBAL_NAME, WindowHandle(Symbol(), Period()));
  
  return(0);
}

int nameea  = 0;

void OnTick()
{
  if(nameea  == 0)
  {
    if(GlobalVariableGet(GLOBAL_NAME) != WindowHandle(Symbol(), Period()))
    {
      nameea  = -1;


    IndicatorShortName("Program is disabled (duplicate is found)");
      Print("Only 1 EA allowed. This one is will not run .");
      ExpertRemove();
    }
    else
    {
      nameea  = +1;
    }
  }
  else if(nameea  == -1)
  {
    return;
  }
  //...
}
