Thank you for your response. Yes, the password was set in Core QT.

The issue is that the password that was set worked to access the smaller amount within the wallet, but not for the larger amount in the wallet. But it wasn't changed in between accessing them. We have both tried it as well as my husband's business partner tried it for us just in case we were typing it wrong. We continue to be able to type this password in to access the smaller amount.
