Help changing sprite graphics when a movement occurs :S

Hello, Im new to construct but have completed the ghost hunter tutorial. I decided to make a similar game but with differnt sprites for each direction (standing still, forword, backward, left, right and walking forword, backward, left and right). I tried creating a event when arrow key down is pressed, spritedownwalking is created and then spritestilldown is destroyed. Nothing happens Is it possible to change your sprites graphic when changing direction if so how do you do it?

Could you post your .cap file so we can see what you did?

Its okay now Ashley, lostmykeys and PR_afk helped me sort out the animations hopefully ill get the hang of it soon if not, ill post back in this topic.
