Can anybody tell me why this insert might not be working.

1. Try printing $DBI::errstr.
2. Use RaiseError in DBI if possible.
3. Use placeholders, and don't interpolate values.
4. We don't have your _execute, so we can't possibly have a clue about what's going on.
5. IMHO, DBIx::Abstract is a better solution for abstracting SQL.
