How to hide certain fields from Preview before submit page?

Hello

The widget at the bottom of my form for a preview. in the settings part, you can select certain lines that don't show in the preview page. I have entered some tags for the selected things as you can see i have tried with {} and without but they still seem to show 

Thank you for your great service

Hello Lee,

In order to prevent certain lines from showing you have to insert the labels and not the field names:

For example, if you don't want to show Date of delivery field, you will have to type Date of delivery in Hidden fields section.

If you have any further questions, please let us know.

Thank you!
