How do I get one object to move towards another object?

I have tried several times, but I cannot get it right! I am trying to make an enemy character who follows the player on the X axis. How do I do it?

In your enemy:
[Always] — [Extractor (player) (x)] — [position (x)]

Thats to get them on top of the player…

Proximity with player, pointat

Always- 4 - velocity forward
