I'm trying to code a program that compares multiple values of two variables (CI and CF). CI contains one variable that can have 1 of 10 values, and CF contains variables which must be solved themselves (and one of these containing a variable that can have 1 of 3 values). After all the computing is said and done, I need to subtract CI from CF and output the values of CI, CF and CF-CI into three tables. I have included the code below. Note that all constants are listed, and the two variables that can have multiple values are 'thick' (1-10) and 'Tair' (-10, 0, 10). Also note that 'thick' + 'a' is actually variable 'b'. My problem is that 'b' and 'Tair' are found in a few equations, that will most likely be buried in functions. Code-wise, I've got it to a point, but to do what from here is where I'm stuck. Any help or suggestions are much appreciated.
