Retrieve information by entering a value

I have a registration form which has a id to it,now on entering only the id I have to display all the values entered in the form.The form id is autonumber which cannot be directly given as a text box so i have taken an additional attribute to store the entered value and then compare it to the form  id which is autonumber.Please help with a solution how to compare these two numbers and get the details

If you are in a microflow, I would try to create a integer variable, parseInteger the value the user entered, and compare the value to the autonumber
