Track number of times form completed by each person

Track number of times form completed by each person

Hello, 

I wonder if anyone out there can help me. The nice guys at Zoho support have tried to help me but unfortunately it doesn't allow me to do what I need. 

I have two forms: 

1. SERVICE USER DETAILS (name, address etc). 
2 WELLBEING

They are linked through a look-up field on the wellbeing form (last name, first name, DOB). 

Each service user will complete the wellbeing form a number of times over a period of months/years. Each time they complete the form, I would like it to capture that this is the first time this person has completed it, the second time, the third time, etc.

Logically I can think of two ways to do this:

1. A field that automatically generates 'REVIEW 1, REVIEW 2, REVIEW 3.....' each time the person completes the form.
2. Show/hide fields 'REVIEW 1, REVIEW 2, REVIEW 3.....' depending on the form submissions that person has previously made. 

Can anyone help me with this please? 

The application is here:  https://creator.zoho.com/lindsay.hodgson/wellbeing-review#

Thanks very much!
