Second half of Powershell Script Ignored

My script writes the UserName from SQL records to a CSV file where the Disable date is less than my check date by 90 days.

After this portion is complete, I want to update the 'Completed' field to 'True' for these same records. The problem is that it appears that the second SqlQuery that does the update is just being ignored.

1. If I run the same Update statement at the top of the script in place of the Select statement, it works fine.
2. Placing obivous errors in the Update statement when it's at the bottom of the script, such as a fake table name, doesn't even generate an error.
3. I've used write-host to display everything and it's showing the correct info.

Thanks,

JB
