PHP Help!

Hello, I am a Newbie at PHP and I have what may be a simple question. I will try and describe my situation the best I can. I am trying to setp up a form that does an automatic execution between mine and another's site. I have a list of tasks that need to be done. They are all the same tasks, but each have different variables from the database, like codes and amounts, etc. When I click on "Perform Now" on one of the tasks, it works perfectly., but then when I clcik on the next task, it stated that I already did that task. It appears that it is using the same info from the last task, instead of updating the form with the new task's info. Even when I hit refresh it says the same thing. The only way I can go on to the next task is by opening an entirely new window. This defeats the purpose of time saving, because if I open a new window, I have to type in my login and password information to even get into the admin section. Then have to click on the link to get tot the page. Then I would have to do it all over again for the over two hundred tasks I have. I hope you can understand what I am trying to do. Is there a code that resets the variables to nill, so that it can grab the new info? Hopefully, you won't need the code that I've used in order to answer my problem, but if you do, I will privately email it to you. Thank you in advance for your help for my situation. Anthony
