When you check your chart of accounts, you can see the error: 'One of the following ranges is enclosed within the other range: Range 1 Range 2'. This means the low and the high numbers of one category account range fall within another range. For example: | Category Account | Low | High | | Product Sales | 4000 | 4099 | | Export Sales | 4080 | 4085 - The first range includes this range of nominal codes. | |
