Snowboarding animations in the event graph, need help!

This is most likely a very simple task but as a novice I am completely stumped.

I am attempting to create some sort of banking when the character turns. In the anim graph I have set up a couple of variables, which when set to true the character will enter the left or right animation depending on which one is true.

In the event graph however I’ve no clue how to find information to decide if they should be true or not. My idea would be to watch if its turning by either watching the “A” or “D” Keys respectively, for an input, or somehow working out if its rotating a certain way then return true to either one. Which I need to convert to a Boolean of: If <0.1 = true for the turning variables.

Sorry if this doesn’t make sense I’ve included some screen shots to help.
