I would like to ask how to write a formula to summarize info on a separate
worksheet within the current workbook.  

Example: Info is on Sheet 1 in C1 & C2, and Sheet 1 in E1 & E2, and I want
to display on Sheet 2 A1 & A2, and Sheet 2 A4 & A5, with a blank row
between A2 & A4 the numbers that are on Sheet 1

Sheet1!
On my list of numbers, I first copied and pasted 200 #'s in B1, and in C1
wrote
the formula =SUM(B1), then in C2 I wrote =SUM(B200), and repeated this 150
times.

Then on Sheet2 so I could print all 150 pairs of answers on one sheet to
easily reference.  

I wrote the following example starting in B1, repeated this 12 times to get
all 150 pairs of answers.  I wrote Down 13 sets of 3 rows, then over to the
right starting in D1, D2, etc.

Column A1                   Column B1
      1                           =SUM(Sheet1!B1) and
                                   =SUM(Sheet1!B2)
A4 is a Blank Row
      2                           =SUM(Sheet1!D1) and
                                   =SUM(Sheet1!D2)
Etc.

I was looking for an easier way to get the info from Sheet1! and Sheet2!
onto my summary sheet;   Sheet3!

This took me about 2 hours.  I hope there is an easier way to do this.

Sorry for being so wordy.
