I am using Armory .96.4 with bitcoin core of .16.3 I have three wallets which two are encrypted ant the other is watching only. The watching has several bit coins and when I try to do a transaction from the offline wallet I get an error that says that The wallet is watching only. Do I need to transfer to one of the encrypted wallets to get it to work with the offline wallet.
I have two wallets that are encrypted and one that is watching only. The watching only has several bitcoins.
Then you don't have the private keys that control the Bitcoin. They are not in the Watch-Only wallet.
Your friend's husband may have written down the private key on paper somewhere very very safe. It might look like this (hexadecimal)
like this (WIF)
or like this (minikey)
Your friend's husband may instead have written down on paper a seed-phrase that looks like

From a private-key or seed-phrase you can create a Wallet that will give you control over the Bitcoin.
Do not ever give the private key or seed phrase to anyone else. Especially not to anyone claiming they can help you.
Somewhere between a fifth and a third of all Bitcoin have been lost forever, partly in circumstances like this. Without the private-key they are unrecoverable. That represents billions of dollars woth of money, if it were possible to recover lost Bitcoin we would know about it.
You need the private-key or the seed-phrase.
If the encrypted-wallets have a wallet-password you do not know, and you suspect those wallets contain the private-key (and therefore control the Bitcoin), you can try looking for a written-down copy of the password or try guessing the password based on what your friend knows about her husband's other passwords. People spend months or years and considerable amounts of money trying this approach.
Do I need to transfer to one of the encrypted wallets to get it to work with the offline wallet.
No, there is nothing useful in the watch-only wallet.
I would be willing to pay for help.
You'll get dozens or hundreds of offers to help, but I'd imagine they will almost all be from thieves and confidence tricksters.
