Hi
i am new using stata, i am having problems with this simple loop uisng if.

gen grade=.

if cnt==484{
replace grade = 1 if SC04Q01 == 1 & SC04Q02 == 1 & SC04Q03 == 1 &
SC04Q04 == 1 & SC04Q05 == 1 & SC04Q06 == 1 & SC04Q07 == 0 & SC04Q08 ==
0 & SC04Q09 == 0 & SC04Q10 == 0 &/// SC04Q11 == 0 & SC04Q12 == 0
 replace grade = 2 if SC04Q01 == 0 & SC04Q02 == 0 & SC04Q03 == 0 &
SC04Q04 == 0 & SC04Q05 == 0 & SC04Q06 == 0 & SC04Q07 == 1 & SC04Q08 ==
1 & SC04Q09 == 1 & SC04Q10 == 0 &///  SC04Q11 == 0 & SC04Q12 == 0
replace grade = 3 if SC04Q01 == 0 & SC04Q02 == 0 & SC04Q03 == 0 &
SC04Q04 == 0 & SC04Q05 == 0 & SC04Q06 == 0 & SC04Q07 == 0 & SC04Q08 ==
0 & SC04Q09 == 0 & SC04Q10 == 1 &/// SC04Q11 == 1 & SC04Q12 == 1
}

the replace commands work well without the loop, it makes the
transformations in all the data set.
but i want to restrict the transformations to only those who have a
value of 484 in cnt.

any ideas why the loop is not working

thank you very much
fernando
