running problem

when i press the uparrow i want 2 things to happen:
1)the player will move forward
2)the players armature will activate the “run” animation

my problem is, that when i press the uparrow, the animation is done once, but when i keep pressing the uparrow the player keeps moving forward, but the animation isn’t played no longer.
how do i do it that by holding the uparrow he will do the animation over and over again untill i will release it?

there are action types:

  1. play
  2. loop stop
    4.loop end

I usually use loop stop…
(press F4 and under the action actuator press on play, then the action types should pop up)
