I really hope the pictures uploaded successfully or this will make much less sense!
Trying to do a simple app, part of working it out, I started off with a page for my self where I can tweak variables, the idea being to see how these change the outputs. However, when I launch my app on my phone and navigate to this screen it crashes every time before the page even opens.
The screen is just a couple sliders and 1 button. When the button is pushed it takes all these values and saves them to the local storage under certain keys (which I assume is like a variable). As you can see, I’ve tried rearranging the code in two different ways and both cause it to crash every time.
Any suggestions much appreciated
