I am trying to rearrange the order in which variables appear in my table. But for some reason, the error "option order not allowed" appears when I run the following code. Is there some conflict between the options that I am missing here?

Code:
eststo: reg gdp consum control vix c.consum#c.vix if rank==1  , vce(cluster time)
eststo: reg gdp consum control vix c.consum#c.vix if rank==3  , vce(cluster time)

 esttab using "./Tables/regression3.tex", replace f  ///
 b(3) t(3) star(* 0.10 ** 0.05 *** 0.01)  /// 
 scalars( "N Obs." "r2_a Adjusted \$R^{2}\$") sfmt(%13.0fc %13.3fc) ///
 keep(gdp consum vix c.consum#c.vix)  ///  
 order{c.consum#c.vix gdp consum vix ) ///
 label booktabs noobs nonotes  interaction("$\times\$") /// 
 collabels(none) alignment(D{.}{.}{-1}) ///
 mtitles("Rich" "Poor")
