Count how often each household member was mentioned per activity

Dear Statalist,
within my survey data set, I asked each respondent who in the household was responsible for specific activities and I would like to know for each household member, how often that household member was named for a specific activity.


I think that I have to loop over the individuals and count how often each individual has been named. I'm just not sure how to do this. The FAQ on"How do I create variables summarizing for each individual property of the other members of a group? (http://www.stata.com/support/faqs/da...ng-properties/) was of some help, but I couldn't get the code running. Stata would not accept the delimit expressions.

by hh_id activity1, sort: gen smex1 = _N activity1<.
by hh_id activity2, sort: gen smex2 = _N if activity2<.
gen byte smex1_n = 0
gen byte smex2_n = 0

forval i = 1 / `r(max)' {
replace smex2_n = (m_hhex_indid == `i' | (j_hhex_indid == `i'))
#delimit ;
qui by hh_id (smex2_n), sort:
replace smex1_n =
cond(activity2[_N] == `i', smex2[_N], smex1[_N])
if person == `i' & smex2_n[_N] ;
#delimit cr
}

Also, I would like to create a variable which counts over both of my activities, so it should contain for each individual how often they have been mentioned within the vars activity1 and activity2.
I would very much appreciate your help!
Best,
Laura
