Write some Software

I need an existing javascript code changed or re-written to suit a further purpose. I play a browser game called Tribal Wars, which has a feature where you can purchase and sell resources for in game currency. When players sell resources it's a fight against everyone else in your area to fill in the form with the amount and click submit first. Currently I have a code which alerts me by audio that there is resources to buy and lets me know how much by putting the amount in the form. But I want it to be taken 1 step further and actually submit it for me so I get a higher success of getting these resources.
