Help: Display collection field in Text Box

I am new to Wix code and have dabbled in other forms of code in the past. I am trying to display data from a collection in a text box. The code I have is below:

.eq(“postcode”, session.getItem(‘postcode’))
.then( (results) => {
let Item = results.items[0]; //see item below
$w(‘#text60’).text = Item
} )
. catch ( (err) => {
let errorMsg = err;
} );

Error for this code is below

If anyone could help that would be awesome. Been stuck on this for some time.

It seems that you are working with numbers on your site, so if that field is a number you need to convert it to a string using .toString(); to make it work as a value in a text field.

You are trying to set the text field to an entire Item :
$w(’ #text60 ').text = Item

To set the text field, make sure you specify the field that you want to display. For example:
$w(’ #text60 ').text = Item.fourHeavyWaste;

I hope this helps.
