TextBoxes not appearing at right position

[Girish Bahri]

I am working on a Word Template that searches for some string in document &
based on that generates textbox with some unique value in a document just
below that text line. The process works fine, except for these:

1. Box position are not fixed, some time they appear at right position, but
not always
2. There are instances when some boxes disappear from the document

Pls. help
Thanks in advance,

G. Bahri

P. S.: I've used Selection.Information to get the current cursor position.
