st: Error when using "diffvars" - xtabond command

Dear all,
I am running a Dnymaic Panel Data exercise, using the xtabond command.
The expression I would like to test includes variables at level and
first differences. When trying to specify this using the option
diffvars() in the xtabond command, I get the following error message:
"" diffvars() may not be specified when performing system estimation ""
I have tried many other different options, but I haven't succeed in
finding anyway to prevent xtabond to difference all of the variables.
So, Does anyone know how to use this "Diffvars()" option properly?
Many Thanks in advance!
Jose
