When I try to sum a column of dollar amounts, it returns 0. I have a column, let's say, consisting of $1.23,$2,87, and $5.55. I enter the sum function in the cell under$5.55, then click on the $5.55 cell, hold the shift key down, and then click on the$1.23 cell. Those cells are then outlined in red. Then I press Enter. The cell where the formula is now turns to the character "0" (without the quotes). I'm doing something wrong, of course, but as a newbie, I can't figure out what that is. Any help appreciated.
