Where to run InvokeRepeating?

I would like to invokerepeating and instantiate some prefabs based on the current (and changing) value of BallController.score

void Start(){
	if (BallController.score>100) 
               {
	    InvokeRepeating("Blockers", 1f, 1f);
		}
                }

void Blockers() {
	if (BallController.score > 100)
		{
		Instantiate(MakinBlockers);
		}
                } 

Currently my code only starts InvokeRepeating(“Blockers”) if the game is stopped and started over again with a score of more than 100. Where do I need to put InvokeRepeating to make it check the score more often?

If you are doing what I think you are, then you need to remove this condition in Start():

 if (BallController.score>100) 

That is, you want InvokeRepeating() to be called all the time, bu you only Instantiate() if the score is > 100.
