what problem that? hoping help, i'm newbie vb.net..

thank you.

try putting brackets around fields / character

proddate, [line/shift], watts, etc...

otherwise, have painfully make sure every field typed in sql string exists in [records] table.

given number of fields in query, think doing select * [records] order pcode enough.

also, make sure use real field name in order clause:

order pcode
