How to flip the sprite for point&click game?

[sean60]

I can get the player move to where I click my mouse but I cannot find a proper way to flip it.

PS.it's a 2d game.

I think my problem is that I am not able to get a proper normalized vector2.
I used "Get position 2d" and store the vector2 variable, after that  "Vector normalize" was added to normalize the variable, then "get Vector2  XY" in order to get the X from it. But the X is a negative number which I assume is not correct
 And the normalized x I got from the "get mouse X" action seems fine. 
Comparing the two X will result in some error.

What should i do?
