How to write a command for nultiple condition with a character variable?

[Phuc Nguyen]

Hi all, in my study, I want to study the subsample without observations from some countries without cutting the sample set

My code is

xtreg TAT_w1 $tatcov_ post1treatvn post1 treatvn i.year1 if not (inlist(GEOGN,"CHINA","INDIA")), fe vce(cluster TYPE2)

In this case I want to study the whole sample without observations from GEOGN(country) are "CHINA"or "INDIA"

However the code above got the message

.      xtreg TAT_w1 $tatcov_ post1treatvn post1 treatvn i.year1 if not (inlist(GEOGN,"CHINA","INDIA")), fe vce(cluster TYPE2)
not not found
r(111);

Could you please guide me, thank you.
