Passing parameter to script through URL and invoke the test

Hi All,
I wanted to invoke test execution from a web page after we click the button and passes the parameter to the script from the URL.
I tried the option given in eggplant manager “Use the link below to trigger an execution of this test from outside Eggplant Manager” but how can I pass the parameter to the script with this URL and my input changes on every iteration. Is there any way to achieve this task?

Thanks in advance!
