@Bjorn_Lindqvist
You really do understand my circumstances - I’m so grateful for you not bashing me for posting that! (tears of joy emojis) Or worse - referring me links to more tutorials that further confuse my already fried brain (if not yet done in by COVID…)
I hope you won’t mind me asking these additional questions:


If I want to increase the number of inputs, I see that they have to be declared beforehand. Is the same true in making the number of hidden layers? (…especially if I need to have 15-levels of hidden layers…)


When making additional hidden layers, must I really have to put in the code for each hidden layer? Or, is it advisable to put the codes for number of hidden layers as a loop?
(That is, if the number of hidden layers is 15, do I have to loop the inputs to the hidden layer code 15 times?)


Regarding the inputs, can a column of values stored in an array pass continuously stream through it?
Like…
all values inside array [N] go through input x0


Or must the ALL the individual values in that array be summed up then pass through an input?
Sum of all values inside array [N] go through input x0
Thanks again for your earlier reply and please bear with me on my follow-up questions…
