Two possibilities that I can think of:

1) you have a variable called AR-DA-08 and do not have a variable called 
AR-DA-07

2) you have a variable called AR (and possibly another variable called DA), 
which when evaluated as a mathematical expression (AR minus DA - 08) 
provides a result, but when 07 is subtracted, an invalid result is obtained.

But, as others have noted, this does not appear to be what you are looking 
to accomplish!
