How do I change an animation based on direction of touch?

I am attempting to make a top-down 4-directional sprite. The issue I have is when I "touch" the screen the sprite will correctly change animation on either the X or Y axis but not both.

It seems that when I click anywhere on the screen the animations begin to compete for each other and nothing plays.

Below is a screenshot of the code.

Please tell me how I can simplify or fix this.

Try Compare Angle

Comparing angle between touch & object is little bit tricky due to maximum angle formed by two is 180 and became negative value when 180 exceeded.

So I will do as follows:

+ On Touch ---> Set animation frame to round((180+angle(Touch.X, Touch.Y, Sprite.X, Sprite.Y))/90)
