Convert type UnityEngine.Vector3' to float' Error

So I have some code where the camera is shaking and my error is:

Assets/Scripts/CameraShake.cs(33,25): error CS0029: Cannot implicitly convert type UnityEngine.Vector3' to float'

The error shows up on the lines where I multiply the x and y variables with the damper, magnitude, and the originalCamPos. If you have any idea why t$$anonymous$$s is happening, it would be greatly appreciated. Thanks!

     public float duration = 0.5f;
     public float speedBump = 1.0f;
     public float magnitude = 0.1f;
 
     void Update(){
         if(Input.GetButtonDown("Fire2")){
             StartCoroutine(Shake());
         }
     }
 
     IEnumerator Shake() {
         
         float elapsed = 0.0f;
         
         Vector3 originalCamPos = Camera.main.transform.position;
         
         w$$anonymous$$le (elapsed < duration) {
             
             elapsed += Time.deltaTime;          
             
             float percentComplete = elapsed / duration;        
             float damper = 1.0f - Mathf.Clamp(4.0f * percentComplete - 3.0f, 0.0f, 1.0f);
             
             // map value to [-1, 1]
             var x = Random.value * 2.0f - 1.0f;
             var y = Random.value * 2.0f - 1.0f;
             x *= magnitude * damper * originalCamPos;
             y *= magnitude * damper * originalCamPos;
 
             
             Camera.main.transform.position = new Vector3(x, y, originalCamPos.z);
             
             yield return null;
         }
     }
