When player collides with object load next level

Hi I need help

When player collides with object how can I get the game to load next level but instead of making loads of scripts how can I make this one re-useable

Thanks

var level : String;
function OnTriggerEnter( hit : Collider){
Application.LoadLevel(“SCP_Level”+level);
}

here u can apply this to a gameObject. when u enter this trigger it will load ur next lvl

my lvlnames are like this “SCP_Level1” so the var level will define ur level just change that numer when u attach the script in the trigger.

hope this helps.
