Yes/No is a Boolean field so it can only be on/off...yes/no. So it'll always be No until you flip it to yes. Rather, create a text field that is 1 character long and set to a Lookup. Enter your own values of M and F. Dian D.

For example, you may have entered text in a numeric field or a number that is larger than the FieldSize setting permits." and putting quotes on value list Row Source gets the same result. Anybody got any other ideas? -----Original Message----- From: mso-bounce@xxxxxxxxxxxxx [mailto:mso-bounce@xxxxxxxxxxxxx] On Behalf Of Cathy.Evans@xxxxxxxxx Sent: 01 December 2005 16:07 To: mso@xxxxxxxxxxxxx Subject: [mso] Re: Logical properties in Access (am using 2000 and 200 3) Thanks for the clarification. To prevent any other entry that M/F, in table design view, set the Validation Rule to: Like "M" Or "F" If you want to also have a lookup you can set the list box value to M;F. hth, Cathy ---------------------------------------------------------------------------- ------------------------- The information transmitted is intended only for the person or entity to which it is addressed and may contain proprietary, business-confidential and/or privileged material.
