    Total Floor Area is showing a NaN

    I have a form which is used to calculate residential Floor Area Ratio (FAR). The form is structured into seven parts as follows:

    Part A: Maximum FAR and Floor Area:

    Part B: Gross Floor Area of the main floors of the main house:

    Part C: Gross Floor Area of the basement or cellar:

    Part D: Gross Floor Area of the attic:

    Part E. Gross Floor Area of all accessory structures except detached garages: (including cabanas, guest houses, caretaker's cottages, pool houses, sheds, barns, or other structures except a detached garage)

    Part F. Gross Floor Area of the garage: (not including basement garages)

    Part G: Total Floor Area:

    The Javascript involved in the calculations is as follows:

    Code:
     
    
    <SCRIPT LANGUAGE="JavaScript" TYPE="text/javascript">

    I have attached the html file as a .txt file for reference, and I have attached a .txt document including all the values I used for testing.

    Why is it showing NaN values? Any help would be greatly appreciated.

    Thank You.

    Ok I have inserted the [CODE] inserts. In regards to my problem I posted, do you have any ideas?

    Re: Total Floor Area is showing a NaN

    Have you tried using debugger and step through the code watching relevant variables?
    You dumped large amount of code and not many people will loook over (some might), so if you can distill the problem to smallest code which exhibits this, it helps to spot a bug or mistake and even might shine the light for you where it breaks.

    Re: Total Floor Area is showing a NaN

    I think the problem is somewhere in here:

    Code:
    function doPartG(){
    //-------------------------------------
    // Calculates G1 & G2
    //--------------------------------------
    	entireForm.G1.value = roundTwo(Number(entireForm.B6.value) + Number(entireForm.C4.value) + Number(entireForm.D16.value) + Number(entireForm.E2.value) + Number(entireForm.F26.value))
    	entireForm.G2.value = entireForm.A15.value
    	
    //-------------------------------------
    // Calculates G4 & G5
    //--------------------------------------
    	if (entireForm.G1.value > entireForm.G2.value){
    		entireForm.G3.value = "Yes"
    		entireForm.G4.value = roundTwo(entireForm.G1.value - entireForm.G2.value)
    	}
    	else{
    		entireForm.G3.value = "No"
    		entireForm.G4.value = "Not exceeded"
    	}
    
    }
    
    
    </SCRIPT>

    The reason I think that we are getting the NaN is because the D16 value is not a number.

    The D16 value that is being used in the calculation is (N/A to this property).

    Maybe if I could tell it that (N/A to this property) is really equal to 0 then it might calculate properly.

    This is javascript not java. Despite the similarity in name, they are completely different programming languages. Try the 'Scripting - Client Side' forum.

    Re: Total Floor Area is showing a NaN

    Without knowing what those values are is hard to see why it happens.

    As I mentioned, try to use debugger and you should see very quickly what are the values for each individual variable. If you have some kind of aversion to debugger, print those values out right before you use it in your calculations.

    I would also suggest to name them something more descriptive, not like C4, B6, etc.
