Hi I'm haveing trouble with creating a array on the server side so far i have this code but i keep getting the error message this.myRSO has no properties can somebody plz help me work out how to create the array?

PHP Code:
application.onAppStart = function(){


this.myRSO.getProperty ("myArray")==undefined){


I know the above code is just creating an empty array but it doesn't even process past the if statment before it errors out.
