Survival

#1
I have an SPSS issue when calculating 1 or 5 year survival via Kaplan-Meier method. When I conducted the study, I receive the mean and median overall survival for the cohort. However, I am having a hard time to find the 5 year survival.
When I examine the life table that is produced when conducting a Kaplan-Meier survival analysis, sometime the tables do not give me the estimate at 60 months but at random intervals. How can I produce a survival table that gives me the estimated survival at 60 months?
