Converting From Send Key Event To Real Programimng.

I designed a macro by gathering information from few posts from here it is supose to go to a website and convert a set of coordenates to another system and copy and paste info in to active workbook. It always ran as expected. My Boss asked me to load this program on his computer (he loved what it was capable of doing). And that was my worse mistake, The code would do all but nothing that it was programed to do. To make the story short, I almost got fired on the spot..
know I need help doing what I was always adviced to do: Avoid using the "Key send event". I am new to programmimg but I would hate to start looking for another job.
