Date Validation Rules for Access?
I am trying to create a validation rule for Access that would try and use other fields to limit entries. So if a field2 is 'yes' then I want my date field to be restricted to jan-may and if field2 is 'no' then my date field to be restricted from june-dec. Is this possible?

Yes if the data is being entered on a form.
Try this
Let's assume your yes/no field is bound to a checkbox called chkD, and the date in entered into a text box named txtDate:
then for the After Update event for that check box, put
Private Sub chkD_AfterUpdate()
If (chkD = True) Then
txtDate.ValidationRule = "Month(txtDate) between 1 and 5"
txtDate.ValidationText = "your own error message 1"
Else
txtDate.ValidationRule = "Month(txtDate) between 6 and 12"
txtDate.ValidationText = "your own error message 2"
End If
End Sub
The "= True" is redundant, but makes the code a little more readable
When you enter a (wrong) date into the text box, the error message containing your validation text will appear when you try to move the focus to another control on the form
Hope that helps
