I'm using Office 2000.  I've set up an excel speadsheet with 40 lines of
contacts (names, addresses, etc.).  I've also set up a main document in Word
2000 as a catalogue file, and I have a next record (Word field) field after
all of the merge fields.

Problem: When I merge to a new document, some contacts are missing.  How do
I get it to include everything.  I suspect it has something to do with after
I sort the spreadsheet.  Before sorting, everything merges fine, but if I
sort in the excel sheet or use the query option in Word, I am missing
contacts (merge data).  Also, once I go forward with it, I can't go back.  
I've also tried copying and pasting into new documents and spreadsheets.
