AFT model time-dependent with weibull distribution

weibullaft<-aftreg(Surv(sta,time,S) ~ TDC1 + TIC1, dist="weibull",
data.frame=Data) 

## aftreg gives an error when I add an ID argument... That should be used
for controlling for time-varying variables.

Error in aftreg.fit(X, Y, dist, strats, offset, init, shape, id, control, 
: 
  *Overlapping intervals for id  2 *
  
From help(aftreg): id If there are more than one spell per individual, it
is essential to keep spells together by the id argument. This allows for
time-varying covariates.
