st: error message about bootstrp

Hi folks,
I did a very simple bootstrap and get the following error:
time-series operators are not allowed with bootstrap without panels, see tsset
r(198);
The BS code is as follows:
cap program drop apese
program apese, rclass
version 12.0
capture drop xalphat ehat
reg y x1 x2 x3
return scalar alphaj=_b[x3]
predict xalphat
predict ehat, residual
gen sdhat=exp(xalphat+ehat)/(1+exp(xalphat+ehat))^2
sum sdhat
return scalar ape=r(mean)
scalar apej=alphaj*ape
end
The running code is: bootstrap apej=r(apej): do apese_bs.do
Thanks a lot!
Wu
