Dear Statalist,

I am using -bssize- from SJ 11-4 in Stata 12.1. All is well with the following three lines of commands:

	bssize initial, tau(0.01) pdb(5)
	set seed 1
	bootstrap, reps(1326) saving(one): sureg (`sequat1') (`sequat2')(`sequat3') 	(`sequat4'), c(1/`k')

I can see the coefficients and their bootstrapped standard errors for all the equations I estimate.

However, when I next type the command 

	bssize refine using one

I get the error message 

	no valid variables found

I fail to understand why I get an error.  I am following the example in the SJ paper I referred to above. The set of commands I use is identical to the ones in the paper (and also to the ones in the help file). 

I searched the usual sources but I couldn't find the answer.  I'll be grateful if someone can help.
