What is the best method to signal the editing in the form above of an table to a user?

To add an entry to the table, a user must fill out the form above and click the Take it button. He can also edit an existing entry by clicking on the pencil. How can you best signal to the user that this data record has then been loaded into the form above in order to be able to edit it?

Is this an understandable operating concept? Are there any other disadvantages?

[EDIT 1 from here] Okay, my problem is a little bigger. I clarify my question. I am already in a modal window for editing the article data record and have to create several conditions again. And I don't really want to put a modal window on top of a modal window.
