Sorry but the sp_start_job stored proc only accepts a single job name.
try:
EXEC dbo.sp_start_job N'Weekly Sales Data Backup' ;
go
EXEC dbo.sp_start_job N'Next Database Data Backup' ;
go
Alternately you could just schedule the jobs, thats what the scheduler is there for.

Nothing in life is ever so complicated that with a little work it can't be made more complicated.
