Call specific actions in script

Hi,

I am using the web Flight reservation application and have used descriptive programming completely.
Divided my script into foll actions - Login, Flight Finder, Select Flight, Book Flight, Confirm Booking (which invokes Flight finder page at end). I do not want to execute Login again in next iteration; but after Confirm booking action, go back to Flight Finder and so on (i am using local data sheets for iteration).
But if i run my script, the foll happens:
Login, Flight Finder, Select Flight, Book Flight, Confirm Booking , Flight finder.
A new instance of IE opens with Login, Flight Finder etc. Naturally the script fails.
How can i execute login action only once and keep looping between Flight Finder, Select Flight, Book Flight, Confirm Booking,Flight finder..etc for every iteration.
Thanks in advance.

Hi, is there nobody who can reply?
Let me re phrase my query.
I have 4 reusable actions - Action 1,2,3,4
Now i want to run Action 1 only once in the beginning (login) and then action 2-3-4 followed by Action 2-3-4 again as many times as required.How do I get about it?
