show a field on submission edit

I have a upload field that I only want to show when the person has clicked on my edit link in their email and opens the form to edit 

Hi there,

Happy to help you today.

To do this you will need to add Get Page URL widget in your form.

Then you have to set up a condition to show the upload field when URL contains "Edit" in Get Form Page URL field.

You can also clone the form below:
