/trigger doesn't work and can't pick up names...

If I do the following in the order with cheats on in Minecraft:
1. /scoreboard objectives add Trigger Trig
2. /trigger Trig set 1
It doesn't work. It says no Trigger Name found Trig even though I pressed T and then Tab to show that Trig is there. I tried add aswell and it still doesn't work. I changed the name from Trig to TriggerPlayer and still didn't work either...
