NullReferenceException when trying to access other GO in script. C#

Questions & Answers
1

Hello guys i’ve been going crazy for the past few hours trying to figure out what i could possibly be doing wrong. I have a fair bit of knowledge in both c# and unity’s librarys. What my method is doing is scanning a List to and accesses the particular country gameobject. After the GO(gameobject) is found it scans the scripts list of objects(Tagobjects). I then attempt to access the GO’s bool variable,however i get a error once i try to read the proviencewindowdisplay script in the gameobject.

foreach(Country country in EnemyCountrysList)//accessing country objects in list
		{
			Country tempcountryinstance = country.GetComponent<Country>();
			foreach(GameObject GO in tempcountryinstance.TagObjects)
			{
				ProvienceWindowDisplay display = GO.GetComponent<ProvienceWindowDisplay>();//display gets component data for Specific GO
				if(display.BorderProvience)//NULLREFERENCEEXCEPTION HERE
				{
					if(tempcounter == 0)
					{
						BorderProviencesList1.Add(GO);
					}
					if(tempcounter == 1)
					{
						BorderProviencesList2.Add(GO);
					}
				}
				
			}
				tempcounter++; //temp counter increment cause a new list to be populated with a different country instances proviences
		}

cause of this problem
No ProvienceWindowDisplay component attached with object.

if attached then soln is:

if(display&&display.BorderProvience)
{
// good luck
}
