Moving Player on Mobile Device

I am making a platformer for mobile devices. I put arrows on the user interface but I don't know how to make it so when they are tapped it moves the character. Can someone help me figure this out? https://flowlab.io/game/play/380358

This seems pretty confusing but I think I can do it. Thank you so much!

you pretty much just copy the moving bundle but using messages
