When I have the engine on running you can smell antifreeze from the engine..but there is no sign of leaks at any possible place visible. But the overflow coolant tank gets low by about a inch or so every couple of weeks? A guy told me it could be leaking in the fire wall going to the heater core in the glovebox?

If it were the heater core you would smell it inside the cab! Check the radiator very closely next time it is driven for awhile then turned off. Have a pressure test done to find leak if needed!
