Could someone tell me what to change for the iEra tile from this:
/*
This level will help you accomplish
these goals:

> Set up your tiles for working with
either the winter, summer, or autumn
tileset.
> It can also clear your current tile defs
(if you are currently using any tilesets
that conflict, they can be removed)

There's no need to make any changes to
this file unless there's a note telling
you to make those changes.

This script does NOT need to be placed
in every level you make; one you use
it in this level, it will work in every
level that starts with "era_".
*/
//#CLIENTSIDE
if (created || playerenters) {
// if you're having problems with other
// tilesets interfering, uncomment the
// following line (remove the two slashes
// at the start):

// removetiledefs;

// This determines the tileset used (currently only summer)
setstring this.tileset, summer;

// do not change the line below!
addtiledef era_tileset-#s(this.tileset)-offline.png, era_, 1;
}
Help would be appreciated and i need to start level-making for IEra  

You need to have the iEra Tileset first, start training with the Era one...
