Thanks! I think I have the balance displayed.

Update:
The Electrumg wallet works great. Moved all coins (including offline wallet) to hardware wallet. You just have to know exactly how to configure your Armory wallet to export the keys to note pad. Then you have to know exactly how to separate and organize the keys before importing them to Electrumg.
Wait. I'm lost with what you're trying to do by dumping your private keys into electrum? Didn't you already move your BTC to a new seed? And aren't you trying to claim BTG?
By importing the Armory private keys into electrumg I extracted the BTG. Yes, I first moved my BTG and BCH to a hardware wallet with a new seed, (just in case the wallet is a trap). And now I have moved the BTG into the same hardware wallet. The hardware wallet Supports BTC, BCH, and BTG.
And I also downloaded the Bitcoin Private Electrum 1.1.1
https://github.com/BTCPrivate/electrum-btcp/releases/ and extracted those coins also. Unfortunately my hardware wallet doesn't support BTCP at this time so I have just left the coins in my new BTCP Electrum wallet.
I have my pre fork Armory private keys organized into separate note pad files stored on a thumb drive. So I can quickly import the keys into other Bitcoin fork wallets, if I want. That way I don't have to go through the procedure in Armory and reorganize the keys for each new coin.
To get the free fork coins you have to download a wallet set up for that particular coin that allows you to import the private keys.
I used HPC's configuration for exporting coins, he partially shows in the post above. To get to that screen you have to go to "properties" for the highlighted wallet and then go to "back up wallet".
Ah, OK. Hadn't noticed that little g at the end of electrumg. Didn't know they had a BTG tool.
