Count Down Timer C# Conversion Script Not Working Help

OK I had this converted from a Java script I had which worked fine, My only problem with the Java script was that I could not find a way after hours of searching of getting my java script to send a message to another script that was written in C#. After much pain I decided to ask if it could be converted into C# I don't get any errors but the code does not seem to work. Can someone with way more code experience than I take a look and see if you see anything out of the ordinary as to why it would not work.

I'm using UI text and NOT on GUI text if that information helps any?

 using UnityEngine;
 using System.Collections;
 using UnityEngine.UI;

     public UnityEngine.UI.Text timeText;
     
     string minsDisplay;
     string secsDisplay;
     
     int mySeconds  = 0;
     
     private float oldTimer;

         if ( FindObjectsOfType(CountdownTimerManager).Length != 1 )     // If one of me already exists I must be a clone, so destroy me (don't feel bad about it)
             Destroy (gameObject);
         else        // I'm the original, so keep me around
