What is wrong with my c# script? The error os ArgumentException(For Android)

If you have any advice please tell me. Thanks :)

The error I am recieving is(I am programming for Android)... ArgumentException: Index out of bounds. TouchManager.touchInput (UnityEngine.GUITexture texture) (at Assets/Scripts/TouchManager.cs:10) ButtonMovement.Update () (at Assets/Scripts/ButtonMovement.cs:28)

The Touch manager script is... It says the error is on line 10
