Hello my problem is the following I have several cells created, with their respective titles each, but when I try to add more iten to each cell I get error, or does not present the value in the cell this is an example of the app 
The question is where this example calculation area is the cell to how I can add another cell within that area without affecting the others, I'm using the code
/
// ViewControllerGeometry.swift
// calculos2

Sometimes only one value presents me in the cell, the other does not show me or I get an error in the code if someone could guide me in that problem.
