Doozie of a question - workbook, formula linking

Hey guys,

So I have this workbook with tons of different worksheets, with
different names. I also have a summary page with summaries of the
answers from these sheets.

Is there any easy way to make the summary formulas automattically
include any new worksheets that are added?

I was thinking if I could do a list of the worksheets, then I could
just tell it somehow to say

= sum({list} for cell b56) - this calcs the sum for all the b56 cells
in that list.

I tried to do this through concatenate, but it comes out as text and
errors. There seems to be no way to link to another worksheet without
pyshically clicking into it (this makes it a pain, since I need to
change every cell for each new sheet) Now if I could get it to just
do:

Say the worksheets to sumarize from are red,blue, green. I want to be
able to list these vertically and have excel do

sum(Red56,Blue56,Green56) and when I add Yellow to the list to just
make it sum(Red56,Blue56,Green56, yellow56)

Anyone?
