Issue resolved. I used the Get-SPContentDatabase cmdlet to view the attached content DBs for my web applications. I noticed that my Portal had 2 content DBs so I double-checked my Web Application setup and realized I had the wrong DB name in my site collection section for both my Portal and MySiteHost. Once I corrected them. I used Dismount-SPContentDatabase cmdlet to detach the extra content database and restarted the script.
