Code wont work, even though the logic seems right to me

I am trying to make a wack-a-mole for two players. They have a 60 seconds to score as much points as possible.

The two scripts are the main an a timer, as follows. I am also trying to make take the timeVallue variable from the second scrip to the first.

Can anyone help?

     void Start()
     {
         p1points = 0f;
         p2points = 0f;
         randomDelay = 0;
         randomNumber = 0;
         Square1.color = new Color(255f, 0f, 0f, 1f);
         Square2.color = new Color(255f, 0f, 0f, 1f);
         Square3.color = new Color(255f, 0f, 0f, 1f);
