Concatenate works only with single cell values. You can use

=CONCATENATE(A1," ",B1)

However, you cannot do something like

=CONCATENATE(A1:B10)

CONCATENATE doesn't work in array functions. Indeed, there is really
no reason to ever use the CONCATENATE function. You can do the same
thing with less typing by using the & operator:

=A1&" "&B1

I am trying to use the Concatenate function to join two columns of text. How
do I get a space between what I'm trying to concatenate?
