In order to shorten the time it takes to make a report look nice, we can use the format painter to first, "copy" the formatting from one field, then "paste" it onto another. Formatting includes everything under the formatting options menu, including things like decimal places, currency symbol, etc.
1. Click on the object you want to "copy" the formatting of.
2. Go to Format | Format Painter on the top level menu
3. Click on the object you want to apply the formatting to
Note: Some versions of Crystal will not have this menu option, but will instead provide a format painter toolbar icon, in the form of a little paintbrush.
