using "OR" in a ms access 2007 query prompt

I have a query that I need the prompt on a field called "charge_code" to allow multiple entries. Without a prompt the field criteria might look like "LA1234 or LA9876". My plight is sometimes there may be 2 entries, sometimes 3 or more and sometimes it just might be one entry.

For your criteria use....

WHERE instr( [Enter list with commas],Chargecode)>0

This assumes that one field value is not wholly contained in another value.

to deal with not finding the correct info, add "," in both sides of the parameters

WHERE instr("," &  [Enter list with commas] & ",", "," & [Chargecode] & ",")>0

Why not make this easy on your users (and yourself as the developer)  and use a multiselect listbox?

listbox doesn't seem feasible for 1.4 million records.
