Hi,
I am trying to use a parameter in one of my queries but consistently get the
following error:
FbException was unhandled
Must declare command parameters.
With this statement highlighted:

Peter,
not an expert myself, but in your code I am missing a statement like:
daDuePacks.SelectCommand = FbCmdDuePacks;

Thank you André

I don't really understand your explanation.
I suppose I really don't understand why it is possible to retrieve data from
