autorefresher

Hello, Im looking for software It needs to auto refresh certain page till certain button apears, or enables to be clickable. When it appears it needs to click it, stop refreshing page ofcourse and on the page that will open afterwards, there will be a box to fill in with number. The number that it will fill in automaticly will be added by me in database, as theres few different buttons on page that can appear so it needs to recognise which one appeard so that it know which number to fill in in next page.
