Sorry, that was just the sound of my programmer head exploding when I saw "Push-Up of the Day.h".

But anyway, that isn't the problem. Never compare strings with == (actually, you are using =, which is even less correct). What you should be doing is this:

if ([mlabel.text isEqualToString:mad:"Knuckles Pushup"])...

It's not necessarily the only problem, but it's the first that I noticed.

Thank you very much. Modding the if statment like you said really worked. Now I have another problem. This App is a Tab View App. I want to add a back button to every page that the begin button switches too. Problem is when I put a back button to Regular Pushup it just shows a white screen. I guess this is becuase Push-up of the day is in a tab view. How do i GO ABOUT FIXING IT.
