I have just put coolant in and now when I run the defrost the tempature guage starts to go down in the cool area. This is only when I turn on derost or heat?

Check the coolant level when the car is cold in both raditor and overflow. The coolant level is droping when you turn the heat on. This in turn causes the coolant to drop. The temperature sending unit is no longer making contact with the coolant due to the drop, causing the gauge to read incorrectly. Try topping it off and Good luck.
