Outlook 2000

Properties / Validation on a field

I checked "Validate this field before closing form."

The Validation Formula is [Amount]

For "Display this message if validation fails:" - "Enter Amount."

The message does not display if field is empty and the form can be sent.

I do not have the "A value is required for this field" checked because if it
is checked, a message displays "A field on this form requires a value." It
does not tell me which field.

Thanks for your help and direction!
