Trying to achieve blank cells in formulas

Two questions - similiar nature!!

1. This formula relies on another cell having the appropriate
information in which it can perform.  However, if nothing is entered in
the cell and I want to copy the formula down the column for future
entried - What can I include in this formula to ensure that if other
cells are empty (nothing to calculate against) that it leaves the cell
empty too.  Presently, I get N/A#

=VLOOKUP(G2,'Data sheet2 '!$A$5:$B$12,2,TRUE)

2. what would the formula be for a simplier calculation i.e =n3*m3
(again if nothing is in n3 what can I add to the formula so it leaves
the cell blank instead of N/A#.

Thanks to anyone in advance!

For 1. try
=IF(G2="","",VLOOKUP(G2,'Data sheet2 '!$A$5:$B$12,2,TRUE)=

for 2. try
=IF(cell="","",your_formula)

Hi!

Excel is quite good on averages!

Try this:

Put 90 in C3
Put 80 in C4
Leave C5 blank
Put 70 in C6
Put 68 in C7

Now put =AVERAGE(C1:C3) in D3
Copy this formula down to D4...D7

Is this what you are looking for?

Now replace the blank in C5 with a 0.  Trouble!

So: if you can ensure that the blank values are really empty, you ar
OK. If C5 is filled from A5 and B5, you could use a formula like 
=if(or(A5=0, B5=0),"",A5/B5) and the same for all the other C cells.

The reason I left 2 blank cells above the columns was, of course, t
simplify the "boundary conditions" at the start of the column. No
essential to do it this way, but it is easy

Preserving Cell Formats in Excel Query
I am doing queries on a large workbook of multiple Excel spreadsheets. When I query the data, the original data formats don't carry through to the query results.

Moving a row from one sheet to another wrongly leaves blank-row artifact.
Moving an entire row within a sheet in Excel XP is implemented correctly: Select the entire row, cut it, go to the target location, and Insert Copied Cells. The target row is inserted (pushing all rows below it down), and the source row is deleted (bringing all rows below it up, as it were). NOT so when the target is in another sheet in the same workbook. Excel inserts the target row correctly, but fails to delete the source row. The row still exists (only it's blanked out). You have to remeber to, tediously, return to the source and delete the blank row. Which means that if you intende...
