Is it possible to display the contents of multiple separate cells in another
single cell?

If the results of several cells say B1, B2, and B3 are the amounts $10, $15
and $20, I would like to display them in cell A1 as follows:

$10
$15
$20

I could do this statically by using text and the 'Alt|Enter' function within
the cell. However, these amounts will change from time to time so I'd like a
link.

Is this possible or not?

Thanks for any help.
