automate form click

I have a form that I use it requires me to initially go to a specific url and log in with a username/password. It then brings up a form that has me click a button to create a time stamp. I would like to be able to script this some how. Basically, I want to be able to go though and enter times and days that I want to log in and to create the time stamp. Once I have done this, I want it to automatically log me in and click the button. This page is hosted on an intranet server, so it will be imposible for me to give you the url. Please resond as I hope to have a solution immediately. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
