Waitforseconds is not waiting

I have this code which is loaded when you finish a game level. It should freeze the time, scale the level completed message, wait 5 seconds and then load next level and unfreeze time. The problem is that the WaitForSeconds is not working. It just loads the next level without waiting. What am I doing wrong? 

IEnumerator WaitingFunction(){
    yield return new WaitForSeconds(5);
}

void OnTriggerEnter ( Collider col )
{
    if (col.tag == "Player")
    {
        Time.timeScale = 0f;
        lvlcomplete.transform.localScale = new Vector3 (1,1,1);

        StartCoroutine(WaitingFunction());

        Time.timeScale = 1f;
        lvlcomplete.transform.localScale = new Vector3 (0,0,0);
        Application.LoadLevel(Application.loadedLevel+1);
        player.transform.position = new Vector3(0f, 0.3519309f, -2.381933f);
    }

Like LearnCocos2D said you have to move the code. Further on to get this working with timeScale = 0 you simply need to let this wait for the corresponding number of frames:

IEnumerator WaitingFunction(){
    int noOfFramesToWait = (int)(seconds * Application.targetFrameRate);
    for (int i = 0; i < noOfFramesToWait; i++) {
        yield return null;
    }
    Time.timeScale = 1f;
    // do my stuff
}

If you have a couple of situations like pausing, additive level loading, game over, fading in and out,.. the next step can be get this more generic:

void OnTriggerEnter ( Collider col ) {
    if (col.tag == "Player") {
        Time.timeScale = 0f;
        StartCoroutine (WaitForNFrames (5f, LoadNewLevel));
    }
}

public void LoadNewLevel () {
    Time.timeScale = 1f;
    // do my stuff
}

IEnumerator WaitForNFrames (float seconds, System.Action executeWhenFinished) {
    int noOfFramesToWait = (int)(seconds * Application.targetFrameRate);
    for (int i = 0; i < noOfFramesToWait; i++) {
        yield return null;
    }
    executeWhenFinished ();
}

Another small thing, maybe you have this already: You reference the player object after calling LoadLevel. Ensure that it is not destroyed when the new level is loaded by using DontDestroyOnLoad.

Try restructuring your code as follows 

WaitingFunction(){
    yield WaitForSeconds (5);
}

void OnTriggerEnter ( Collider col )
{
    if (col.tag == "Player")
    {
        Time.timeScale = 0f;
        lvlcomplete.transform.localScale = new Vector3 (1,1,1);

        StartCoroutine(WaitingFunction());

        Time.timeScale = 1f;
        lvlcomplete.transform.localScale = new Vector3 (0,0,0);
        Application.LoadLevel(Application.loadedLevel+1);
        player.transform.position = new Vector3(0f, 0.3519309f, -2.381933f);

                }

You start a coroutine that waits 5 seconds without doing anything while the OnTriggerEnter code continues to load the level instantly.

You should move the code that should run after the wait time has passed inside the coroutine:

IEnumerator WaitingFunction(){
    yield return new WaitForSeconds(5);

    Time.timeScale = 1f;
    lvlcomplete.transform.localScale = new Vector3 (0,0,0);
    Application.LoadLevel(Application.loadedLevel+1);
    player.transform.position = new Vector3(0f, 0.3519309f, -2.381933f);
}
