embeded calc with same parameter names but different values

Oct 14, 2014 at 8:17 PM
((a - b)*c) where a and b are data points and c is (a + b) where a and b have different values than the first a and b. The values come from a database that holds the calculation(s) and there parameter values.

My thought is to do "something" to fill out the expression then finally add the original calc and GetResult.

thoughts?
