Logic Engine Integration & Results Page

KneeIQ — Logic Engine Integration & Results Page | £800 | Bubble.io

What’s built
A clinical MSK knee assessment tool for doctors and allied health professionals. The multi-step wizard (demographics, mechanism, symptoms, examination, special tests) is complete and live in Bubble. The landing page is also done.

What needs building
Two things only:

  1. Logic engine integration — A JavaScript scoring engine (provided as a complete .js file) needs wiring into a Bubble workflow on the wizard’s Submit button. The engine receives all wizard answers as inputs, scores 13 diagnoses using if/then gate logic and weighted scoring, and returns a structured JSON results object. Full documentation provided including an input schema, a step-by-step Bubble implementation guide, and a worked scoring example.

  2. Results page — A structured clinical output page that displays the JSON from the engine. Elements include ranked diagnosis cards (each with likelihood band, evidence strength, mechanism/symptom/examination breakdown, test evidence table, management plan, and uncertainty factors), a conditional combined injury panel, a safety netting section, and a collapsible copyable assessment summary with an editable clinician rationale field.

What’s provided

  • Complete JavaScript engine file (drop-in, no coding required)
  • Bubble implementation guide PDF covering every custom state, workflow step, and element binding
  • Full results page element mapping table (30+ fields, each mapped to its engine output field)
  • Scoring walkthrough with worked examples
  • Logic specification document

Skills needed

  • Solid Bubble.io experience — Repeating Groups, custom states, conditional visibility, URL parameters
  • Comfortable with the Toolbox plugin (Run JavaScript, JavaScript to Bubble)
  • Able to handle nested JSON binding (JSON Object or Floppy plugin)
  • No clinical knowledge required — everything is documented

Budget: £800 fixed
