I am sorry you are not able to locate the buttons to click. I suggest accessing the link on a computer and advise you to clear the browser history, cache, and cookies of your browser.
I have provided an article here that should walk you through the process of clearing the history, cache, and cookies of your browser.
If you are still unable to access the buttons after going through the above steps, I recommend reaching out to the Enrollment section of your school district who should be able to assist you further with accepting or declining the lottery position of your daughter at the district.
