i think the problem is, is that its not clear what you are trying to achieve
so, if you have taken the three character bit, then your query will show this, in the results.
if you want to limit the number of rows, based on this number, you need to put something in the criteria row of that column, to get what you are looking for.
on the other hand if the 3 figure number relates to another table, then you need a second query, based on this query, to link the 3 figure number ot your other table
ie you probably cant do it directly in one query
