Yes, and if you are in TopBraid Studio, you have a full Script Debugger panel 
at your disposal, allowing you to step through each line of code and checking 
what the values of the variables really are.

As Richard says, maybe some of still returned as objects (such as LiteralNode) 
instead of JS numbers.

Hi GaBriella,

One way to debug is to add console.log after each assignment:

let fNode = ...
console.log(fNode)
let media = ...
console.log(media)

And then have the Script Console panel open. Whenever console.log is executed 
in an ADS script, the argument is added to the output in the script console.

In JavaScript, NaN means “not a number” and is often the result of doing maths 
with a value that is not a number (such as a string, or an undefined value, or 
an array). I remember bumping into NaN when I thought I had accessed a 
single-value property, but it was actually multi-valued, returning an 
array-like value.

I have a field where I am trying to infer a decimal value using the following:

let fNode = wfschema.asAnalysisPosition(focusNode)
let media = fNode.media
let sum_media = media?.reduce((cur, val) => cur + val.mediaDevelopmentHours, 0)
let perfSupp = fNode.performanceSupportMaterials
let sum_perfSupp = perfSupp?.reduce((cur, val) => cur + val.developmentHours, 0)
let estTime = fNode.estimatedTimeToCompletion
if(media && media.length > 0 && perfSupp && perfSupp.length > 0 && estTime) 
(sum_media + sum_perfSupp) * estTime

It is returning an NaN and I cannot figure out why. I have verified that each 
of the properties it is looking at has a decimal datatype. How else should I 
troubleshoot?

Please let me know if additional information is required. Thanks!
