delete that second one... it's jsut too wrong to fix. The first one... I don't know how you managed to mangle that one... but you've managed to mix two connection types there. First thing you need to decide is if you're connecting to a database on a SQL Server instance, or if you're wanting to connect to a database file... once you decide that, you then need to delete the parts that are for the other connection type. If you need help pop over to https://www.connectionstrings.com/sqlconnection/ for a properly formatted connection string.
