Mathf.Clamp does not work at all.

I am using C# and I am trying to clamp a velocity value that will increase when I press down on my accelerate button. The code is as follows:

 if (Input.GetKey(KeyCode.W))
         {
             currentVelocity += forwardAccelerationRate * Time.deltaTime;
             maxVelocity = 50.0f;
         }
         else if (Input.GetKey(KeyCode.S))
         {
             currentVelocity += reverseAccelerationRate * Time.deltaTime;
             maxVelocity = 10.0f;
         }
         else
         {
             currentVelocity -= deccelerationRate * Time.deltaTime;
         }
 
         currentVelocity = Mathf.Clamp(currentVelocity, initialVelocity, maxVelocity);
         Debug.Log(Mathf.Clamp(currentVelocity, initialVelocity, maxVelocity));

where

 initialVelocity = 1.0f;
 currentVelocity = 0.0f;
 maxVelocity = 5.0f;
 forwardAccelerationRate = 2.0f;
 reverseAccelerationRate = 0.5f;
 deccelerationRate = 0.7f;

My currentVelocity variable just continues to increase no matter what.
