I cannot understand why I am getting the NullReferenceException?

NullReferenceException: Object reference not set to an instance of an object TouchHandler.TouchControl () (at Assets/Script/TouchHandler.cs:78) TouchHandler.Update () (at Assets/Script/TouchHandler.cs:39)

I get this error and i cant figure out why. I thought some fresh eyes might help, anyone? Thank You.
