Change Movespeed based on Mouse Input

Basically have a vertical 2D platformer and the code will hopefully better explain what I am trying to do. However what I want is if I click on a positive X position, I want positive movespeed, if negative, then negative.

I currently have this implemented, but only the first if statement works. My Platform generator has a similar set up with If/Else if statements, so I am curious why this doesn't work?

     void Update () {
 
         grounded = Physics2D.IsTouchingLayers (myCollider, whatIsGround);
 
 
         if(Input.GetMouseButtonDown (0))
         {
 
 
             if (grounded) {
   
 
 
                 if (Input.mousePosition.x > 0) {
 
                     myRigidbody.velocity = new Vector2 (moveSpeed, myRigidbody.velocity.y);
                     myRigidbody.velocity = new Vector2 (myRigidbody.velocity.x, jumpForce);
                     Debug.Log ("option 1");
                 } 
                 else if (Input.mousePosition.x < 0) {
                     myRigidbody.velocity = new Vector2 (-moveSpeed, myRigidbody.velocity.y);
                     myRigidbody.velocity = new Vector2 (myRigidbody.velocity.x, jumpForce);
                     Debug.Log ("option 2");
                 
                 }
 
             }
         }
     }

I also think that movespeed should be adjusted based on distance, but that is a later issue I will tackle.

Hopefully that made some sense! Cheers to anyone who helps.
