Minecraft multiple data tag command help

So I am making an adventure map but it won't let me use multiple data tags.

The command I'm using is

/give blackbelt999 minecraft:stone_button 1 0 {display:{Name;"place on diamond block to begin"},{CanPlaceOn:"diamond_block}

But I keep getting this error message:

Data tag parsing failed: Expected non-empty key at:..."place on diamond block to begin"},<--[HERE]

what is wrong with this command?

There are multiple problems with your command:

1) it's Name: and not Name;
2) you need to close the display tag before you can pu in the CanPlaceOn tag.
3) the CanPlaceOn tag expects a list ([]) of things, even if there is only one thing in that list.

Fixed command:

/give blackbelt999 minecraft:stone_button 1 0 {display:{Name:"place on diamond block to begin"},CanPlaceOn:["minecraft:diamond_block"]}
