Agree with the notion that something was renamed. Some people use AutoName Correct (others avoid it) and Access often makes the required correction when you rename something. However, one place it will not rename something is in the subform control link to the main form. Check the properties of the subform control to see if the subform is linked to the main form by Query1.ORDERID
The more we hear silence, the more we begin to think about our value in this universe.
