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 this 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;
		
		while (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;
		}
	}

x *= magnitude * damper * originalCamPos;
y *= magnitude * damper * originalCamPos;

originalCamPos is a Vector3 not a Float.

Did you mean to do the following?

 x *= magnitude * damper * originalCamPos.x;
 y *= magnitude * damper * originalCamPos.y;
