Form doesn't merge input fields from prefilled url

Using

https://form.jotform.com/PRCC/prcc-202021-refunds?name[first]=Betty&name[last]=Norman&[emailAddress]=bhnorman%40telus.net&[eligibleAmount]=166

Only fills in first and last name - can't get it to fill in other fields using advanced | unique name

My account PRCC - form is https://www.jotform.com/build/210436769120250

It seems you are not using the field name correctly. Please note that you need to use the field name without the brackets. Please use the following URL with parameters to populate values in the form fields:

https://form.jotform.com/PRCC/prcc-202021-refunds?name[first]=Betty&name[last]=Norman&emailAddress=bhnorman@telus.net&eligibleAmount=166
