Can you be more specific?
How your data is organized?
Have you -steset- correctly your data?

Subject: st: survival analysis

I am doing survival analysis on stata. After declaring the data set to be
survival data I tried to run a proportional hazard model, but it gives me an
error of "no observations". 
Can anyone tell me why this may be?
Thank you all.
