V-Lookup variation query

Hi,

I am having an issue with comparing columns of values.

Basically I have a table similar to the below except with a couple of
thousand lines.
Either the first column will have a value that doesn't match with the second
column or vice versa so basically I need Excel (2002) to begin at the top and
compare the values until it finds a mis-match, extract that value (perhaps to
another sheet) and continue down the columns doing the same thing until the
end.

46,898,748.00 46,898,800.00
2,365,412.00 2,365,412.00
15,465.00 15,465.00
4,864.00 4,864.00
41,564.00 54,156.00
48,642.00 41,564.00
1,564,968.00 48,642.00
4,589,846.00 1,564,968.00
5,852,852.00 4,589,846.00
6,458,456.00 5,852,852.00


At the moment I manually do this so, using the above example, I would go
down the list until the amount of 54,156.00 which I would cut and paste into
a different sheet and then delete the cell with that value so the rest of the
values on the right move up and match until the final amount on the left of
6,458,456.00 which would also be removed as it also doesn't have a match.

With a couple of thousand items this is very time-consuming. I'm not sure if
a v-lookup would help or perhaps a macro but any help would be greatly
appreciated.

Many thanks in advance

Niall
