awk Division By Zero Bypass

Hi Friends,

I don't understand why "a" is always being printed as zero, when I execute the following command.

Code:
awk '{if($6||$8||$10||$12==0)a=b=c=d=0;else (a=$5/$6);(b=$7/$8);(c=$9/$10);(d=$11/$12); {print $1"\t"$2"\t"$3"\t"$4"\t"$5"\t"$6"\t"a"\t"$7"\t"$8"\t"b"\t"$9"\t"$10"\t"c"\t"$11"\t"$12"\t"d"\t"$13,$14}}' input
