Sharepoint MOSS and submiting data to external web service

All I need is help and coaching and being guided for doing this task for a client: We have a form in a sharepoint MOSS called:? [login to view URL], the form has a Save button that has a click event that? saves some data on the form to a list and also saves those data to a session variables. The Save method, after,? calls [login to view URL] to an other page called:? [login to view URL] Here is what I need to do in the Load event of the page:? [login to view URL] I need to call the Insert method of? an external web service, passing to it the data from the session, like this? : [login to view URL](session["value10"], session[value2],....etc) How do I do that pls? Thanks :) ## Deliverables p.s: All I need is guidance, not actual programming, just guide me with what to do. I will be doing the programming myself. This is an? urgent task ASAP Thank you
