[Other] Only getting a beep noise?

[pichu in the cardboard box]

I'm new at rom hacking so bear with me and my newb question.
I wrote the following script(Don't worry, it's short and simple)

Spoiler:

#dynamic 0x8000c6
#org @start
lock
faceplayer
msgbox @talk 0x6
release
end

#org @talk
= Don't even think about touching\nthis mailbox!

Then I assigned this script to a person event. But when I went next to the person and pressed the A button all that happened was a beep noise. Just the noise. No lock effect, he didn't face me, I was able to move afterwards, no message, and no crashing.

Programs I used: Xse 1.1.1, FSF(Free Space Finder), A-map 1.95

FSF settings: Free-Space Byte- FF, Needed Bytes- 250, Search Interval- 16,
Search from offset- 800000

Debugged the script already using Xse's debug button.

I set the unknowns to 3 in a-map
Your help is appreciated! :)
