Checking a GUI.Textfield (C#)

I want to check if the player entered the right word in a

 GUI.Textfield(new Rect(x, x, x, x), x, x);

I’ve tried:

if(CorrectAnswer1 == "paspoort"){
   GUI.Toggle(new Rect(x, x, x, x,), x, x);
}

However, this doesn’t seem to work. And although I don’t get any errors. It won’t show me the checked toggle button I want.

I’d be really great if someone could help me. The script has to do with Dutch word checking. Therefor one might not understand the word “paspoort”.

save what GUI.textfield returns and check it to see if its correct:

void OnGUI()
{
	String userInput = GUI.Textfield(new Rect(x, x, x, x), x, x);
	if(userInput == "paspoort")
	{
   		GUI.Toggle(new Rect(x, x, x, x,), x, x);
	}
}
