A solution to last week's challenge can be found here!
Tires: they smell bad and can be expensive, but we all need them. For being a basic piece of technology, they have a huge impact on arriving safely at your destination.
For instance, the "contact patch" refers to the amount of a tire contacting the surface of the road. The size of a contact patch has a huge impact on stopping distance, traction, and even fuel economy. It's a similar story with tire height.
When looking for new tires, it can be useful to get information about a tire's width and height. Many sites have "tire calculators" which allow a user to enter a tire's size in a standard format and view more information on that tire. The standard format for tires is tire width in millimeters, a percentage of that width as the sidewall's height, and the radius of the rim in inches (e.g. 285/70/R17 is a 285mm wide tire, with a sidewall size of 199.5mm (285*.7), and fits on a 17" rim).
For this week's challenge, create a chained app to allow users to enter tire size information and view the additional information on file. Update the next field after the user makes a selection so that only existing options are available.
Your app interface should look similar to this:
My solution! Went with an intro question as well so that I didn't have to have manual inputs in my first drop down (used the first app to create the grouped values for the second chained app to use in the dropdowns).
