Sorry for the vague question. It seems that the root of the problem comes from the format on the imported field "Letter Code". With a general format in excel, it viewed some as numbers and some as text so importing that file to Access seemed to confuse the query. When I converted the excel file...
Sorry, I am new at this. My table contains a database of records pertaining to a direct mail project. There are over 800,000 names (or records) included and each record is assigned a “letter Code”. This letter code field contains both numbers and letters such as:

Thanks for the reply. Being a bit new to this stuff I am not sure I completely understand the syntax but if I play with it for a while I may just get it!
Thanks again....
