Hi, Martin,

my original example involved the following condition: if length(make)>12
Since "if foreign" is a simplier condition and it still allows to see
the bug, I replaced the if-condition in the final posted code, but
apparently not everywhere.
Should be: count if foreign
22.

Best,
   Sergiy Radyakin
