find/replace

Win XP, Word 2003

I exported a field in FileMaker Pro. It is a repeating field with two dates
in one field. I thought I could import the field into Word and find the
marker that separates one date from the next and do a Replace All and put a
Tab between the two dates and then put the dates into two different fields,
the way they belong. I have the field in Word and there is a small
rectangle between the dates. So far nothing I have used as a Find has
"found" it, except for White Space (^w), but when I do a find ^w and replace
^t, Word replaces thousands of the occurences but the demon white rectanges
remain. I even tried copying and pasting the rectange into the Find box but
that is not working.

I have a posting on a FileMaker Pro board to see if someone can show me how
to separate the dates from with FileMaker, but it seems I should be able to
do it from within Word.

Does anyone have a suggestion???
