Log.Message("carrier exists"); 
}
else {
Log.Message("carrier "); 

}
}

If you don't like nested conditions, you may use the fact that JScript uses short circuit conditionals. The code in this case may look like this:

if ((navigate.WaitAliasChild('carrier', 5000).Exists) && (navigate.carrier.Width > 0))

  // sucess

else

  // failure
