New service tax registration

Dear All,

I have taken a service tax registration against GTA , business oxiliary and service & maint., while selection of services I did not found any service to select, find out only one service "other than nagative list" and I had selected this one.

Now My query is,  at the time of online payment I will have to select only one service "other than nagative list" or will select all these three services.

please reply as early as possible.
