Setting a constrained input

- [Instructor] Sometimes it's valuable,…even necessary to constrain input values…to a set range.…For example, if you're filling orders…for the new iPhone, and you're willing to fill an order…between one and up 100,…then you're going to want to constrain the user's input…to something within that range.…You're also going to want to make sure…that nobody accidentally enters something…other than an integer.…So, for example, they can't order 3.5 iPhones.…

So, let's set that up.…The syntax here is getting complex enough…that this is a good time to invoke and rely on…the expanded section of the properties panel…for different form elements.…With a number selected in my code,…I can define high, low, and step values.…First, I'll start with the basic code.…Next, I'll invoke the Properties Inspector.…I'll select the input type in the code,…and the Properties Inspector responds by providing…context helpful options.…

Let's choose a suggested value, and…we want people to order the maximum number,…so we'll go with 100.…The minimum they can order is one.…
