The Web Forms functionality lets you build complex multi-page, multi-entity wizard-style forms on your Power Apps Portals. And while there are a ton of options, it’s not uncommon to run into situations where you can’t do everything you want with configuration, so you might need to resort to a bit of JavaScript (and maybe even Liquid). One of those situations is if you want the source entity for the next step in your Web Form to be a record related to the entity of the current step.
