Hello,
I have a problem, I do not know how to make the values that I entered in the analytical application are returned together with the calculations that are inside the formula tool. You can download the .yxwz file. I show the result that I want, an image of the work flow and the inputs that I entered. I don't know if what I did is okay.
What I want (oil, 54 and the results of formula tool)

workflow

Inputs (oil and 54)
