Sorry Tony,
I always find it hard to explain a problem.
The problem is that when I run a saved query, in one of the fields in the answer table has a blank field, yet in the table I have queried, there is a value.
Table Structure:
Primary Key Customer_No N
ExamDate D
Title A6
FirstName A12
LastName A20
NoandStreet A56
Subburb A20
Town A25
Postcode A8
Mobile A20
WorkTel A15
HomeTel A15
DoB D
Doctor A15
TestType A20
Amount $
VAmount $
OldPx A3
SeenBy A25
ListNo A16
Required A10
Notes M50
RecallPeriod N
RecallDate D
Collected D
EMail A30
Organisation A15
Family S
RecallType A50

This will result in some records in the answer table having nothing in the 'RecallPeriod' field, yet there is a value in the Cust1 table for that record. The 2nd posting was an observation that in a different table some of the records have dissapeared. My question is why has this happenned and is my copy of Paradox10 corrupt and if so what dio I need to do to put it right?
I hope this is now clear.
Many many thanks, Lewy
