I'm not sure what you're trying to do but will following code work for you?

CLEAR
Local OutputCounter, Start, Finish
NodeCount = 37
Start =  NodeCount * 2 + 1
Finish = NodeCount * 3
For ActivationCreator = Start To Finish
	CodeLine = [W] + Transform(ActivationCreator) + [_] + Transform(ActivationCreator + 1) + ;
        [ =  W] + Transform(ActivationCreator) + [_] + Transform(ActivationCreator +1 ) + ;
	[ + LearningRate * Node] + Transform(ActivationCreator + OutputCounter) + ;
	[Error * Node] + Transform(ActivationCreator) + [Activation]
	? CodeLine
Next ActivationCreator
