Jeg mener at have scriptet til sneen, men det sner IKKE????
Hvad gør jeg galt i scriptet og hvor sætter jeg det ind i HTML kodestrengen for at få det til at sne, der er et eller andet der hele tiden går galt. Jeg har naturligvis gemt en "snow.gif" på stedet, men er det det rigtige sted den er gemt.

koden ser således ud:
