Hi, Can anyone help me to write a program/solution; I want to take input from customers from dynamic page and want to store in collection.

I want to store in collection, and display comments for the dynamic page itself not for all dynamic pages. I develop a form and connected it with collection, and to display data, I’m using repeater. But it didn’t stored user comments according to dynamic page field in collection, and I am unable to identify comments for individual page.
Here I have attached my page input form and output display.

Here is snap shot of my collection,

I’m almost blank in programming, looking for kind advice.
