How to add a URL variable parameter?

How do I get the the colon to appear so that the url is like “/requests/:requests_id/[request]”?
The page won’t actually let me type a colon in the input box.

Hi @rasen58

The [Request] Icon you see at the end of the url indicates that the page will be looked up for a record - the dropdown above that lets you pick the field to use to lookup the record (token is selected in the screenshot).

But why do some of my other page urls have a colon “:”?

@rasen58 I’ve checked a few apps and I don’t see this behavior if you invite me to your app ( I could take a look at your page.
