Hi @Herman 

You can do this with a Klaviyo form and using a custom profile property.

For example, let’s say you call the custom profile property ‘porridge_consumption’.

1. Add single-select radio buttons for 4 weeks, 6-weeks, and 8 weeks (see below) to that custom property in your form. 
2. Add a text input box beneath this for ‘Other’. This also should push its value to ‘porridge_consumption’
3. Embed this form on the web page and link to it from your campaigns/flows.
4. The ‘porridge_consumption’ property, along with their chosen values, will get added to a contact‘s profile once they submit the form.

Some considerations:

• ‘Other’ is a free text field, so they may add some value other than just a number, e.g. 6, 6-weeks, 6 weeks, misspellings etc, so harder to select for in the campaign and flows. My suggestion would be not to use the text input box and instead extend the radio buttons to include greater values and omit ‘Other’. You then control the values
• If you do go down the ‘Other’ approach, you should test this as it’s possible a contact selects, say, 4-weeks, from the radio buttons then enters 6 to the text input box - I think Klaviyo will capture the 6 rather than the 4 as the custom property value, but I’m not sure!

If your actual survey is more extensive than your example, you may want to consider an app for that, e.g. Tyepform or similar.

Hope that helps
