I have created three tables on a word page.  The first two tables are for
different processes and total a sum as the last field.  The third table is a
summary of the totals of the other two tavbles and will use the totals from
the other two tables as a sum total of it's own.  According to your help file
I need to first assign a bookmark to the field I want (source) and then call
it in the corresponding field in the summary table (target).

Trouble is that no where in the help area does it show the bookmark syntax
in the source field or in the target field.  Can you please provide some
examples?  My source field already has the formula =C4-D4 which works fine
but no matter how I place the bookmark I get "!syntax error" in that field.

Thank you in advance for your assistance.
