I think I got it.
Did you put this:
ADD/
<questholder/name/Kill Bobo/notestring/Bobo must go. Find him and kill him/objective1/KILLNAMED,Bobo,1/autoreward/true/rewardstring/@bag/ADD/gold,200
Instead of this:
GIVE/
<questholder/name/Kill Bobo/notestring/Bobo must go. Find him and kill him/objective1/KILLNAMED,Bobo,1/autoreward/true/rewardstring/@bag/ADD/gold,200
The second one is the correct one. I think you just mixed up the ADD and GIVE commands.
Edit: It could also be what Arte said
