Hi.. anyone.. who could solve my issue.. i have a panel for 2011 and 2016.... the religion should be same but for me it changes... if its 1 in 2011 it should be 1 in 2016; if 2 in 2011 it should be 2 in 2016 .. so i want to clean my data and erase those households which have difference in religion in both years.. i did try some command but it didnt work.. can some help...

i tried this but this is wrong i am missing something...
by HHID (year), sort: keep if religion==1 & year==2011 |religion==1 &year==2016 & religion==2 & year==2011 |religion==2 &year== 2016 & religion==3 & year==2011 |religion==3 &year==2016
