How to Recommend Products Based on Numerical Inputs¶

A quiz cannot link a recommendation to a number the customer types. Ask for a range instead of a figure, and the answers become finite enough to carry products.

The walkthrough shows the Built for Shopify version of the app.

Why an open-ended number does not work¶

A Number or Date question lets the customer enter any value at all. There is no answer to attach a product to.

"What is your age?" and "How big is your room?" look like useful questions. Because the customer can type any figure, neither one can drive a recommendation.

Use finite choices instead¶

Ask the same thing with a multiple-choice, dropdown or slider question. Offer ranges, or a fixed set of values, so that every answer is one you can link products to.

Age ranges

Change "What is your age?" from an input field to a dropdown with these choices:

Under 20
21-30
31-40
Over 40

Year of birth

Where the exact value matters, list the values themselves. Change "What is your year of birth?" from an input field to a dropdown with one choice per year:

1990
1991
1992
1993
1994
1995
1996

use dropdown question to ask year of birth

Once the answers are finite, you can:

Upvote products, variants or collections from each choice
Switch the question between dropdown, multiple-choice and slider in the Block settings
Edit the labels in the Choice settings
Set up Jump Logic or Display Logic from the customer's answer

Quiz Copilot can suggest the ranges

In the Built for Shopify version, Quiz Copilot turns a broad question such as "What is your room size?" into ranges for you. It also suggests the follow-up questions to go with them.

For room size, that might be:

Less than 50 sq ft
51-100 sq ft
101-150 sq ft
More than 150 sq ft

use quiz copilot to generate room size ranges

Custom calculations¶

The app cannot calculate a result from a number on its own. A quiz that works out a BMI, a dosage or any other figure needs custom JavaScript and a developer.

The script reads the quiz answers, works the result out in JavaScript, then writes it into an HTML element on the results page.

How to add JavaScript to the quiz has a worked BMI calculator.
