Cheers for the advice Mike,

I'm not too hot with using excel but whenever I try to use the advanced
filter option it doesn't seem to work.

I highlight the columns and go through the advance filter options but end up
with the same list again minus the first row under the headers. Bit stuck at
the moment.

Darren,

A couple of steps.

1. Create your unique list of parts.
Select your parts list, the top row must be a header, then
Data|Filter|Advanced filter
Select copy to another location
Check unique items only
Enter a location to copy to (a single cell) I'm going to use D1
Click OK and you should now have a list of unique items.

2. This in E1 and drag down to get your totals
=SUMIF($A$1:$A$5,D1,$B$1:$B$5)

I have a list of two columns consisting of part number and quantity, some of
the lines contain duplicate part numbers.

Example

Part Number Qty
311 10
311 5
312 20
313 5
313 5

Is there any way I can merge the duplicate part numbers into one line whilst
combining the quantites to read as follows?

Part Number Qty
311 15
312 20
313 10

Have a very large database to work through and this would make my life a lot
easier :0)
