Subtract positive number from negative number
I have a query similar to this:
SELECT Sales.ThisYear - Sales.LastYear AS SalesDifference FROM ThisYear, LastYear; This works fine if they are both positive. However, I have an instance where the sales for this year is negative and last year is positive: ThisYear: -80,000 LastYear: 20,000 Result in Access: -100,000 when it should be -60,000. So how can I get it to subtract a positive number from a negative number? |

Subtract positive number from negative number
What kind of business rule would result in -60,000 rather than the correct

Subtract positive number from negative number
That was just an example. You could have the first month of the year
with a credit on account and comparing that with the first month of last year, you have this scenario. So instead of analyzing this in terms of business, can you answer my question? Essentially, what I am looking for is a Variance function of some sort that will show the difference between two numbers, does it exist? |

Subtract positive number from negative number
Never mind...I'm using the Abs() function and it worked.

Not wishing to incur your wrath further I don't understand why you have negative sales ???
