st: Error re xline in stgest -

["Friedmann, Erika" <efrie002@son.umaryland.edu>]

I am getting an error about incorrect specification of ()xline in stgest:  option xline() incorrectly specified.  The program appears to run correctly but does not produce the graph. 

showing the details of the iterations the last line before FINISH is

psi=1 Z=-27.43 esthi=-4 estlo=. upphi=-4 upplo=. lowhi=-4 lowlo=. stop=0
estOK=1, lowOK=1, hiOK=1


 The results of the G-estimate  also give (95% CI     . to -1.500)  which may be related to the problem.
I have compared my syntax to the syntax of the examples (which run correctly) and produce the graph.  

My syntax is 
stset RBC_COUNTER if HX_RBC == 0 , failure(DIED ==1) exit(DIED ==1) id(ID2)
stgest   EX_TX ex2catlt26 un_lenal un_esa un_hma  FEMALE agecat65to78 agecat79pl agecat2xfemal agecat3xfemal /*

Any suggestions would be greatly appreciated.
