I am building a form with reactive form, but i have some nested group inside group, and for that nested group i have only validation required on input.

QUESTION
So I am very new to the world of JavaScript and have been trying to write a simple piece of code. It is to change Celsius into Fahrenheit. (Just the Celsius * 9 / 5 + 32).
I want to enter the Celsius number into the UI and have the answer shown in the DOM (for now - I will change it after so it is shown in the UI after hitting enter.)
But every time I enter the number and click "enter" the DOM shows me NAN.
I know this is probably very basic for most people on this website, but I am new, and any help would be incredibly appreciated.
I have already searched online and found people mentioning parseInt() - but it does not seem to make a difference.
Also, I would like to keep this code as basic as possible - so the way it is now, without the addition of "for loops" and "if else statements".
Here is the code:

Answered 2018-Oct-21 at 09:03var c = parseInt(document.getElementById("celCount").value);
