I am having a series of recurring problems, so I think I need to read
something and I hope someone can point me to a good resource.

I have made a macro that copies various "template" sheets from one
workbook to another. I have a bunch of "presentation" sheets that are
nicely formatted and "data" sheets that have all of the calculations.
The "presentation" sheets refer to cells and names in the data sheets.
And the data sheets refer to a named range that exists in the new
workbook.

All of the copying works just fine, but I am having problems with
both links and names. Sometimes, but I can't figure out when, the
copied presentation sheet refers not to the copied data sheet, but to
the old data sheet in the presentation workbook. And sometimes, but I
don't see the pattern, the data sheets do not refer to the named range
in the new workbook, but refer to some (non-existent) named range on
the sheet itself. When I hand delete that name, the sheet works, but
when I programmatically delete it the whole process gets messed up.

I am asking for a solution to this problem (which is probably not well
enough described, but I did the best I can), what I would like is
something that gives me a solid understanding of how Excel handles
these things, when links and names update, when they don't, how it
works, etc.

TIA
