Random Number Generator Error

I have been reading up for a while on randomness and I decided to give it a shot for a project. I have built the random number generator and I have no errors in the console itself but overtime I hit the generate button it changes the display to read "0". Any suggestions?

Code: using UnityEngine; using System.Collections; using UnityEngine.UI;

 public class RandomGenerator : MonoBehaviour 
 {
     public Text display;
     public InputField minimum;
     public InputField maximum;
 
     private float min;
     private float max;
     private float random;
 
     public void Randomize ()
     {
         float.TryParse (minimum.ToString (), out min);    //convert input field to a float for use in the "Random.Range" function
         float.TryParse (maximum.ToString (), out max);    // ^ ^
 
         random = Random.Range (min, max);    //generate a random number
 
         display.text = random.ToString();    //display a random number on a Text object
     }
 
     public void ResetVariables ()
     {
         minimum.text = "";
         maximum.text = "";
         display.text = "";
     }
 }
