Setting a Yes/No check box problems

[newtoAccess]

I am trying to use a update querry to set a Yes/No check box. in a table. to all yest and the to all now.

UPDATE [Name-Address] SET [Name-Address].Requires_Printing = No, [Name-Address].[Do NOt Print] = No, [Name-Address].[has been Printed] = "yes"
WHERE ((([Name-Address].F_Name) Is Not Null));

It is finding what I want changed but not changing the field to Yes

It is not working, any suggestions?

Does taking the quotes out from around "yes" help?

I tried both with and without quotes.
The query finds all the data that I am looking for but does not change the Yes/No box.

Try -1 or true.
