maya dynamics

Hi,
I have to prepare some dates falling down in a dish, these dates have to enbg or flinch a little bit to inside when colliding with the dish.I tried to make the date as lattice, then i gave it a soft body feature, finally i added a spring to it and with few changes in attributes i got to my target but when i duplicated my date. the new date didn't fall or move at all, i even tried to make a new date from zero as the first one but this also didn't worked.I hope someone could help me.
Thank you all.

Have you applied gravity to it?

Hi dTb,
yes sure i have applied gravity to the first date and when i have duplicated the date i have connected the new one with the gravity field in dynamic relationship editor, but it didn't fall at all, i even tried to connect the new date with a new gravity field for its own, which also didn't work. I hope someone could help me.
Thx.

Can you duplicate this situation in a simpler form?
Create a sphere add gravity so that it falls and then copy it.
If it doesn't work try different methods until the copy falls like the original.
Then apply the working method to your date.
