Dear all,
I'm having problems trying to generate a variable of count from a local and a loop. I need to count the number of times a subject has chosen number 2 across 6 variables. Then, to generate a variable with the number of times the option 2 has been selected.
Here my code:

(id: id of subject)
gen count2=.

local var var1 var2 var3 var4 var5 var6
foreach x of local var{
replace count2=count(`x'==2), by id
}


The result says: "error" unknown function count"

Any suggestions on this. I'd appreciate very much.
Best
