You mean char(1), right? How can you have a varchar(1)?

Why not a checkbox labelled 'Multipack'? Then, the code that assigns the
parameters for your search just says

if Checkbox1.Checked then
param_multipack = 'Y'
else
param_multipack = 'N'

(It's even simpler than this if you are using Delphi/CPPB and IBO...)
