Bob, thanks for your reply.
The cells that I was trying to format were in a column of figures in a spreadsheet that I had cobbled together to use as a check register for a checking account. The spreadsheet contains, among other things, columns for recording the amounts of debit and
credit items (such as checks and deposits), and also a column for showing the running balance.
In the column for debits and in the column for credits, the content of the cells is typically a numeral that I type in manually, for example 9.7 or 100. Some of the cells in the column do, indeed, contain text, since I have created descriptive headings
(e.g., "Debits") with lines or borders beneath them. (But I wonder whether that could be the explanation for the trouble I've had, since I have experienced essentially the same difficulty when I have tried to format not only a whole column, containing mostly
numerals but also a few cells of text, but also just those cells in a column--say the 6th through the 500th cell--that contain [or that should contain] only numerals.) I am able to set the formatting in such a way that even though I only type in, say, 9.7
or 100, the program shows numerals to two decimal places in the cells that appear in my spreadsheet. So if I type in 9.7 or 100, the cell displays 9.70 or 100.00. (What I want is for the formatting to be for currency, and not just for numbers, so that the
cells will display $9.70 or $100.00 when I type in 9.7 or 100, for example. It's not a really big deal for me that I can't always do that without multiple repeated attempted formattings of a few cells at a time, since the arithmetic seems to work correctly,
and since I know that all the figures in the spreadsheet represent dollar amounts.
The contents of the cells in the balance column, however, is different, as you'd expect. I use a simple formula. If, for example, I want the balance to be displayed in column H on line 10, and there is nothing entered on line 10 in the debits column (column
F) and if there is 100 entered on line 10 in the credits column (column G), then I take the balance from column H, line 9, subtract the amount in the debit column (actually there's nothing there to subtract, so Excel generates an error message in the form
of a green flag in one corner of the cell I'm working on, but I can select multiple cells and tell Excel to ignore the error), and add the amount in the credit column. My formula, in this example, reads thus: "=H9-F10+G10 (without punctuation marks, of course)."
I'm not sure that I understand what you're asking when you write, "[W]hat currency format are you selecting, and what does the cell look like before and after you have formatted it?" But I'll take a stab at it.
After selecting some cells and choosing Format>Cells . . . on the Menu bar, a dialog box appears, and under the Number tab, there is a list of different number format choices in a white window. I highlight "Currency" (but when the formatting doesn't work
and I go back to see what it says, I usually see "Number" highlighted, so I suppose that is a default selection). There are also little menus, I guess you'd call them, shown under the Number tab in the dialog box where you can choose the number of decimal
places to be displayed (I always choose 2 when doing a spreadsheet of this sort), the particular currency symbol to be displayed ($), and how negative numbers are to be shown (I prefer to use parentheses, rather than a minus sign, and to have the negative
numbers shown in a black font color, rather than red). When the formatting works, the cell in the spreadsheet into which I've typed, for example, 100, and which shows 100.00, before formatting, shows $100.00, after formatting. When the formatting *doesn't*
work, the cell displays 100.00, both before and after formatting.
Sorry for the length of this, and I appreciate the help.
