Can you use a var to load a level?

I’m trying to make a level loading capsule that will load the next level. But to do this with my current script I have to rewrite it and make a new script to load a different level.

function OnTriggerEnter (info : Collider) 
{
		if (info.tag == "Player")
		{
			Application.LoadLevel("Level Name Here");
		}
}

I was wondering if there is some way to use a var to load the level instead of rewriting the script. Thank You!

var levelToLoadString : String = “Level Name Here”;

function OnTriggerEnter (info : Collider)
{
	if (info.tag == "Player")
	{
		Application.LoadLevel( levelToLoadString );
	}
}

I beleve it is something like this

function OnTriggerEnter (info : Collider) 
{
       if (info.tag == "Player")
       {
         Application.LoadLevel(1++);
       }
}

This should load the next level
