Movement behaviors not working?

I must be doing something stupid here. I have an actor and added the "4 way movement" behavior to it. I add the actor to my scene. When I test game nothing moves when I press the arrow keys. I have my actor on the top layer of the scene. The bottom layer contains tiles I have set to no collisions. Is there another step besides adding the behavior to the actor? Do you still need to add any events to wire it up? I verified in game settings that the controls are set to the arrow keys.

Check to make sure it saved the controls I have been having  problems with it not saving them

I have the same error once in a while... here an behaviour which i downloaded prevented my movement to work (even though this behaviour wasn't 'active' or programmed somewhere).

What i did was publish > flash, and played the flash which showed me an error log with the behaviour mentioned. in this case it was "sidescroller sword attack".. when i deleted that behaviour from my stencyl, my hero started walking again.

Make sure to add the behaviors to your actor BEFORE adding them to your scene.

I swear I tried re-adding the actor to the scene yesterday but tried it again this morning after reading your replies and it worked. Thanks everyone.

You can also double check if you did by double clicking on your actor, go to the inspector panel and enable customize. There you find a list with the attached behaviors. You can also fine tune your variables here.
