Have you installed the 'Time' library?
Time Library

And the DS1307 library?
DS1307 Library

Arduino Time Library

You sure have a lot of problems. You need to spend a little time learning more of the basics before getting into these semi-advanced projects.

Looks like you missed Step 9:

 9. Next, download Arduino Time library and DS1703RTC library zip files through the “Sofware Required” section, Part II.

@missnisa, just one other point. When posting your error messages, it's better to copy the message and put it between code tags rather than attaching a screen shot, as recommended in section 7 here: how to use this forum
