/summon falling sand not working and giving wrong error messenge

When you use /summon FallingSand ~ ~ ~

{Time:2(and changed it to 100),TileID:35,Data:14,DropItem:0}

it will summon a falling sand entity and say that it was successfully created but it never shows up,and if it is truly summoned successfully it is invisible till it stops moving

What I expected to happen was...:
When I type /summon FallingSand ~ ~10 ~

{Time:2(and changed it to 100),TileID:35,Data:14,DropItem:0}

into a command block and powered it, and it created a falling sand entity that looked like reed wool, and it outputs that it was successfully created

What actually happened was...:
I type /summon FallingSand ~ ~10 ~

{Time:2(and changed it to 100),TileID:35,Data:14,DropItem:0}

into a command block and powered it, it outputted that it was successfully created but it never was created.
