You must be using an old version of awk. Try gawk or nawk instead.
Not sure why you have moved the loop outside of awk, which is very inefficient.
Also, you can pass variables to awk on the command line like this...
Code:
awk '{for(n=3;n<=NF;n+=2) if($n) print v1,v2,v3,$1,$n,$(n+1)}' v1=$var1 v2=$var2 v3=$var3 file1 > file2
