Conversion pixel on_sent_ok

I wanna set up a facebook conversion pixel for a form i have. I found a video showing that i need to make a thank you page and there i should put the code in.

But the command at the additional settings part (on the form settings page) doesnt work:
on_sent_ok: “location.replace(‘http://noiessegszivarvanya.hu/koszonjuk’);”

What am i doing wrong? Is there any easier way to set up fb conversion pixel to a form?
