Strange when I open this with IE, I get undefined instead of Andre, Andre. But I get the correct function on firefox.

Only IE9 and other modern browsers have support for ecmascript 5.  Thats why you get undefined for the returned value.

There are two links towards the bottom of the Week 1 material that lead to tables showing what is compatible where.
