Hi,

i have a column that joins a series of other columns to creat a unque key
for a table data I have in a sheet. when I then use sumif or countif
against
the concatenated column it says there is more than one the same and the
sumif
produces the same total for a number of lines. visually looking at the
unique
key column, I can clearly see they are different.

ideas?
