NULL means "I don't know" and <<NULL>> in a textmerge returns nothing.

In my VFP 9, it returned .NULL. as the second argument, which no
server would understand :)

try:

SET NULLDISPLAY TO 'NULL'

before the textmerge.

Also, this might work better if you formatted the date you are
inserting using DTOS and wrapped it in single quotes.
