Adding parameters

Hi all,

I’m trying to build a flex front end which sends a few parameters to a train timetable site - station, period and direction and this then returns the time the train will be at the station!

I’m trying to add the above parameters in AS3 like this

[COLOR=red]var params:Object = new Object() ;

//use values selected by user in the combo boxes
params.STATION = station.selectedLabel ;
params.PERIOD = period.selectedLabel ;
params.DIRECTION = direction.selectedLabel ;[/COLOR]
[COLOR=navy]NB I have 3combo boxes for the user to select from, they’re called[/COLOR]
[COLOR=navy] - station[/COLOR]
[COLOR=navy] - period[/COLOR]
[COLOR=navy] - direction[/COLOR]
[COLOR=red]//create an HTTPService object named service
var service:HTTPService = new HTTPService();[/COLOR]

[COLOR=red]//set the properties of the service object
//url is where to connect
service.url = “[/COLOR][COLOR=red][/COLOR][COLOR=red]”;
[COLOR=red]//connect to the URL and pass the name-value pairs int The parameters object
[COLOR=black]For some reason the parameters aren’t added to the request? Does anyone have any ideas what I might be doing wrong or can anyone advise me on a better way of doing this?[/COLOR]

Thanks a mil for any help in advance,
