How to write a script for a dynamic page in Load Runner?

Question

Software testing

Good day!
The question is. There is a resource test.youplace.net
You need to write a script for Load Runner that emulates passing the test on this link with the conditions: enter "test" in the field, the longest value is selected in the radio or lists.
The problem is that the pages are dynamically generated by the server, i.e. constantly filled with a different number of text fields, radio buttons and lists. The total number of questions (pages) in the test is also not static.
How to approach writing a script for this beast? So far, just started working on LoadRunner. I have no idea where to start this task .. please help
