Attention Redstoners

I need help! What is wrong with this command again?

I'm a little rusty on redstoning :P

/give @p sign 1 0 {BlockEntityTag:{Text1:"{\"text\":\"Glass sign \",\"color\":\"white\",\"clickEvent\":{\"action\":\"run_command\",\"value\":\"/give @p[lm=1] wool 1 12 {display:{Name:\\"Smelly dog droppings\\"}}\"}}",Text2:"{\"text\":\"Want some diamonds?\",\"color\":\"aqua\",\"clickEvent\":{\"action\":\"run_command\",\"value\":\"/xp -1l @p[lm=1]\"}}"},display:{Name:"Glass sign"}}
