Lerp Animation Problem

Dear Forum,

I am an experienced 3D animator but only a C# beginner and I have a (probably) very simple problem w$$anonymous$$ch I can´t solve on my own.

In a nutshell:

I have 4 objects (players) and three buttons placed between them. On clicking the buttons I want the objects left and right of the button to switch their positions. Due to the fact that the objects will be passed from button to button I need to check their positions and then decide wether to move them or not. The buttons call the SwitchPos() on click and the script is placed on a parent empty game object and checks the objects by their tag "asset3_objects". Currently I only have one if clause running checking if an object has transform.x equals 4 and needs to be moved to 7

I use the following script:

 using UnityEngine;
 using System.Collections;
 
 public class asset2_master_v2 : MonoBehaviour
 {
     public GameObject[] players;
     public void SwitchPos()
     {
         players = GameObject.FindGameObjectsWithTag("asset3_objects");
         for (int i = 0; i < players.Length; i++)
         {
            // Debug.Log("Player Number " + i + " is named " + players[i].transform.position.x);
             if(players[i].transform.position.x==4)
             {
                 Debug.Log("Object Number" + i + "fits");
                 private float timeElapsed;
                 private float lerpDuration = 30f;
                 private float startValue = 4;
                 private float endValue = 7;
                 private float valueToLerp = players[i].transform.position.x;
                  valueToLerp = Mathf.Lerp(startValue, endValue, timeElapsed / lerpDuration);
                  timeElapsed += Time.deltaTime;
                 }
             }
         }
     }

The Debug Log tells me that the object fits the position. Now when I add the Lerp components t$$anonymous$$ngs start to go sideways and I get the error codes:

 Assets\scripts\asset3\asset2_master_v2.cs(28,15): error CS1519: Invalid token '.' in class, struct, or interface member declaration
 
 Assets\scripts\asset3\asset2_master_v2.cs(28,36): error CS1519: Invalid token ';' in class, struct, or interface member declaration

Where do I go wrong? I am probably pretty close but I am still learning and do not have the necessary knowledge to solve t$$anonymous$$s on my own. I have read a bit on the Lerp function but the tutorials and documentation cover topics w$$anonymous$$ch are a lot more complex than t$$anonymous$$s.

Thank you and best regards
