Few things about the SQL string

1. When adding a string variant to the SQL it needs single quote before and
after the value
2. When adding a Date variant to the SQL it needs # before and after the value
3. When adding a Numeric variant to the SQL it doesn't need anything.

So, in your Update SQL the AmtPd variant which is Numeric (currency) doesn't
need a single quote before and after the string

Try:
mySQL = "UPDATE Roach SET Roach.AmtPaid =" & AmtPd & ", Roach.Status = '"
& Status & "' WHERE roach.roachlastname = '" & LName & "'"

**********
Also, it's important to set the warnnings back on aftre you run the SQL

DoCmd.SetWarnings True

Or, run the SQL using
CurrentDb.Execute(mySQL), dbFailOnError

Without setting the warnnings On and Off
