Passing id through url to modal and update table

I have a problem, i was working on this for a few days and i am stuck. What i want to do? I want to pass $id through url to modal, witch opens on click and opens table with data that i can edit/update from mysql, using php! When i press edit i get data and person id in url but modal is not opening. I think my script/jquery is wrong, can someone look and help me.!!

When i press edit button i get this in url but nothing opens?!?!
