checked or unchecked?

Hi,



Im trying to run a query to show results based on if an item has a certain value in one field, it works fine, but then i also want to select if an item has a value i another field, its a yes/no value which is a checkbox, could anyone tell me what i need to insert into the query criteria field if i want the result to only show if its unchecked?



Thanks
