Hi Shawn,
Maybe I'm still not getting the picture. What I'm
seeing is something like the following, where you have
text strings in cols B and C and you want another column,
say D, to contain the concatenation of the text in cols B
and C:
A B C D
1 abc def abcdef
2 ghi jkl ghijkl
3 mno pqr mnopqr
4 ... ... ......
If this is true, then you don't really have to use the
CONCATENATE function; in D1 type: =B1&C1. That formula
can be copied down col D for as many rows as you want.
Now, your example is a little confusing, making me think I
don't have the complete picture. It seems you're trying
to string together the content of up to 20 cells, and each
grouping follows a DIFFERENT pattern than the one before.
If that's true, then you have no choice but to do a manual
construction for each case.
If you're trying to do something more elaborate but that
follows a PATTERN, then you need to give me more info.
For example, if you want each successive row to contain
the previous concatenation plus the new one, then you
could, say in D2, type: =D1&B2&B3 to get abcdefghijkl.
Keep in mind that a cell has a limited text capacity (256
chars , I think); if you exceed the limit then you'll get
an error or truncation. I'd like to work through this one
with you. Post back.
