Hey guys need a little guidance. I'm making a clock with code this guy supplied on his website, I have the same board, screen and RTC so I thought it should work but I get so many errors. I can post the errors but that's literally 30 pages of them. Something simple has probably gone wrong causing a ton of issues.
If anyone could shed some light on the situation that would be greatly appreciated 
Hope I posted the code correctly and gave enough info...... I'm new here haha I tried.
