Hi, I need to use a formula array to sum a list of numbers, which are the minimums from two columns. However, using MIN inside my formula array seems to return just the MIN over the whole set.

For example,
A B
1 5
4 6
3 2

So what I actually want to sum is 1, 4 and 2.

Logically, I thought the function should be:

{=SUM(MIN(A1:A3, B1:B6))}
but this just returns the min of all numbers.

Can anyone suggest how I might do this??? Thanks in advance.
Peter.
