I want to have my start shopping button enabled after a user selects a state and school, then have the link for that button direct to the url of the school they selected on the dropdown. Right now, the button will just reload the page I’m on, rather than take me to the page of the school they selected.

    // Define schools data
const schools = [
  { name: "HLS Louisville", url: "https://highlandsuniforms.com/louisville/", state: "KY" },
  { name: "HL Cottage School Louisville", url: "https://highlandsuniforms.com/hlcs-louisville/", state: "KY" },
  { name: "HLS Beaufort", url: "https://highlandsuniforms.com/beaufort/", state: "SC" },
  { name: "HLS Billings, MT", url: "https://highlandsuniforms.com/hls-billings-mt/", state: "MT" },
  { name: "HLS Charleston, SC", url: "https://highlandsuniforms.com/charleston-sc/", state: "SC" },
  { name: "HLS Summerville, SC", url: "https://highlandsuniforms.com/highlands-latin-school-summerville/", state: "SC" },
  { name: "HLS Ft. Myers, FL", url: "https://highlandsuniforms.com/hls-ft-myers-fl/", state: "FL" },
  { name: "HLS Houston", url: "https://highlandsuniforms.com/hls-houston/", state: "TX" },

(Edit)

Since your form really isn’t submitting data anywhere, actually "submitting" shouldn’t happen in the first place.

The button element has a default type of submit. If you want to use it just as a button without submitting your form, add type="button" to its HTML.

Now your rendered School Select dropdown is actually storing the school’s associated URL as each option‘s value, not the school name, so your whole .find() function isn’t working correctly. But, you don’t even need to find a match in the array anyway because you can just navigate to the URL stored along with the school name.

See working example below, but choose the first state and the first school because I have changed the URL in your array so that it will navigate because Stack Overflow won’t allow navigation to the school sites you’ve listed.

// Define schools data
const schools = [
  { name: "HLS Louisville", url: "https://example.com", state: "KY" },

But really, you shouldn’t be using a button for navigation in the first place as it will cause problems for those who use screen readers. You should always use hyperlinks for navigation, but you can style them to look like buttons, like this:

.button {
  width:50px;
  height:20px;
  border:1px solid #808080;
  background: #e0e0e0;
  padding:5px;
  border-radius:4px;
  text-decoration:none;
}

.button:active {
  box-shadow:2px 2px 1px grey;
}

<a class="button" href="http://example.com">Click to go!</a>
