custom number format

[smelton]

I created a custom format to accomodate a credit card number, after i enter the number the last digit is displayed as 0 no matter what number i have put in. EX: 1111-1111-1111-1113 displays as 1111-1111-1111-1110, HELP

You must *pre-format* the cells as Text, before entering your data,
OR
Enter an apostrophe (') as the first character in the cell.
The apostrophe will be visible in the formula bar, but *not* in the cell.

Excel only stores 15 significant digits, as explained in the following
MSKB article:

XL: Last Digits Changed to Zeroes When You Type Long Numbers in Cells

You'll have to store the number as text, as Ragdyer described, and type
the hyphens yourself.
