If you are using blueprints, here is the code to make the character move (It is showing those warnings because I have not yet setup the axis mappings) :

For setting up the axis mapping go to edit and project settings. Under engine go to input and click on the plus button in the axis mappings(Make sure that you have set up the scale properly ie: for keyboard input if you are gonna use the W,A,S,D keys set the scale of S and A to -1.0.) :
