Message on locked door

[MaTPlays]

Hellos!
I've got a problem with the script which adding a message to a locked door.

I changed name of a door to: door3

I wrote in the PlayerInteractCallBack: DoorLockedPlayer

Then i typed in my .lang file:
<CATEGORY Name=“Messages”>
<Entry Name =“msgname”>It is you, the grandson? Please, go get a sack of potatoes for dinner. It should be outside, first on the right, next to apples. The key to the main door in the dining room.</Entry>
</CATEGORY>

And in my .hps:

void DoorLockedPlayer(string &in entity)


{
if(GetSwingDoorLocked("door3"))
{

SetMessage("Messages", "msgname", 0);

}
}

I've got a script for opening door with a key, maybe that's a problem, but idk how can I edit it.

help please!
