Can't get global integer variable through script

SkyTree

How do I get global integer variable? Using 1.50f AC unity 5.2.4
I'm trying this

using UnityEngine;
using System.Collections;

namespace AC
{
public class VarableTest: MonoBehaviour {
GVar MyVar;
// Use this for initialization

void Start () {
        MyVar= AC.GlobalVariables.GetVariable (228);

}

// Update is called once per frame
void Update ()
{
        if (MyVar.IntegerValue = 20)
        {
            Debug.Log ("test");
        }

}

}
}
It's giving me this
Assets/VarableTest.cs(21,38): error CS1061: Type AC.GVar' does not contain a definition forIntegerValue' and no extension method IntegerValue' of typeAC.GVar' could be found (are you missing a using directive or an assembly reference?)

if I use
if (MyVar = 20)

it gives
Cannot implicitly convert type int' toAC.GVar'

The Scripting Guide is for the current release - it won't apply for such an outdated version.

Read "val" instead of "IntegerValue", and you comparison checks require two equal signs:

if (MyVar.val == 20)
