st: cttost error: not sorted

[Eric Grodsky <esgrodsky@ucdavis.edu>]

Hi all-

I have a file of count data that I have declared as such in Stata. When 
I try to convert these data to survival-time data I get an error r(5) 
not sorted. Anyone know what might cause this error and how I can get 
around it?

Here's the output:

. ctset
    dataset name:  c:\temp\temp.dta
            time:  term
        no. fail:  totxfer
        no. lost:  censored
       no. enter:  ssn_start
              by:  collegeid race2

. cttost
not sorted
r(5);

. d
