I can't work out how to edit the numbering style for captions (with inclusion
of the chapter number).
The problem has been trying to change the separator in the caption number.
In one case I had decided on the form "Figure 4.1" etc., and then wanted to
change that to "Figure 4-1", etc.
In another case I had selected a hyphen as the separator ("Figure 4-1") but
found that Word kept changing the hyphen separator to an en-dash ("Figure
7€“1). So in that case the problem was also to try and force the caption
numbering to use the hyphen. (So that's really two problems I have.)
Right-clicking and going to "Define new number format" doesn't do it. And I
can't a way to change the separator within the field code, because the code
itself doesn't contain the separator.
So far my only solution has been to try deleting the initial caption and
then reinserting it with the correct separator. But that seems to create a
new set of problems because Word apparently still continues to see the
deleted caption which throws out the numbering sequence. (I guess that makes
a total of three problems!)
Any guidance will be much appreciated.
