How to pass a function with the same argument multiple times and return values in variables?

Question

The problem I have is I created a function which really is some kind of database.  Basically a bunch of:
if (a.value == "this number"){
b.value = "this expression";
Inside the form are 2 dropdown lists that return numerical values which I want to process through that function and put the return value inside separate variables.
var a = this.getField("OPE003.EVEN.1.MIP");
Mip(a);
var result1 = Mip();
I tried to overwriting *a* to process the second field
a = this.getField("OPE003.EVEN.2.MIP");
Mip(a);
var result2 = Mip();
result1 and result2 are put in an array, joined as a string.
Doing so, I always get the last processing twice as the final result.
Can I use a function as a batch processing tool that way?

Answer 1

You are right, I changed the code to what you said but how do I pass another value through my fonction so I can get Result1 and Result2?
is it
var a = this.getField("OPE003.EVEN.1.MIP");
var b = this.getField("OPE003.EVEN.2.MIP");
var result1 = Mip(a);
var result2 = Mip(b);
var c = new Array[result1, result2]
