new to this and got error code help to solve please

ive just started today trying to make a game so im doing the ball game to try and get the hang of it.

Assets/scripts/playercontroller.cs(10,48): error CS0119: Expression denotes a type', where a variable’, value' or method group’ was expected

that is the error they have given me and my code is using UnityEngine;
using System.Collections;

public class playercontroller : MonoBehaviour
public float speed;

	void fixedupdate ()
		float moveHorizontal = Input("getaccessHorizontal");
		float moveVertical = Input.GetAxis ("moveVertical"); 

		Vector3 movement = new Vector3(moveHorizontal,0.0f,moveVertical);

		rigidbody.AddForce(movement * speed * Time.deltaTime);


i dont know how to fix this error. please help. thanks.

void fixedupdate()
float moveHorizontal = Input(“getaccessHorizontal”);

This is all wrong.

void FixedUpdate()

FixedUpdate is a Unity specific function call and is Case Sensitive.

float moveHorizontal = Input.GetAxis("moveHorizontal");

Input is not a function but a class that has functions for retrieving values from particular input.

I suggest you follow some tutorials on programming in the C# language before you tackle more difficult tasks as you are obviously missing alot of fundamental concepts.
