@glendy277: that means your level is too low. it probably has "lvl ???"? as firefrye explained above, you're doing so little damage, the game just doesn't let you attack yet. level up a few times, and you'll be doing fine against the hornet.
@nothing951: the number of gp required for a mission is the number of gp you still need to earn, not the total. so if you now have 16 gp, and for a mission it says: '4 gp required", you have to have 20 gp in total.
wow, people are really getting lazy here O_o we are so spoiled nowadays by those big budget games with tutorials and hints and tips etc. that a lot of you can't figure out a game for yourselves anymore! c'mon people, it's part of the game, finding out what does what! anyway, this is a great game ^^ 5/5
