Thanks, Jun :o)
You're great ... it helped. What I do not understand at all yet is the meaning of kakari in this context. From my kanji dictionary it is something between multiply and taxes ... I can make a (little) sense of it, but if you could spare the time for a little explanation, I'd appreciate.
PS: If you could also help out with other readings for the kanji for shikko so I could convince my IME to display them ... (?)
