Refill forms for editing...

[H.Castorp]

I finally managed to add a 'Location:' row to the calendar-postsheet (basically, i duplicated all the 'event title' stuff in post.php&calendar.php&calendar.template.php and renamed it)

It works great, SMF is inserting and pulling the info from the database correctly and showing it in the Calendar..

But i just can't find the piece of code, that refills the form with the already existing information, when i click on the red star to edit the post... 

Anyone got a hint please? I'm so blind...
