Script Not Permanently Hiding Sprite

[VenomousViperKin]

I am using XSE and followed a YouTube tutorial to write this script.

#dynamic 0x800000

#org @start
hidesprite 7
fanfare 0x13E
msgbox @talk1 0x6
givepokemon 0x100 0x19 0x44 0x0 0x0 0x0
waitfanfare
setflag 0x1202
release
end

#org @talk1
= You obtained a COMBUSKEN!

When I interact with the person event, it is supposed to hide the sprite, display a text box, and add Combusken to my team.
When I interact with the person event, here is what actually happens. It disappears, displays the text box, and I am unable to check my party if Combusken is there so I am assuming it doesn't actually add it. It is supposed to be a level 25 Combusken with a rare candy as a held item. After I take my first step after interacting with the event, the event reappers.
How do I get the event to do as intended?

What Map editor do you use?
You need to give flag to the NPC in Advance Map / HexManiac Advance
In AMap, there was Person ID, thats where you put the flag (1202)
In HMA, its FLAG on map editor, you put that flag (1202)
and i assume that flag 1202 is free /unused flag, so you can use it.

I got it so the sprite stays disappeared after moving, but I still can't view the Combusken. Is there something that needs to be done before Pokemon become visible in the player's party?

Did your Pokemon Menu, already appear? if not, you need to setflag for showing Pokemon Menu (when press Start).

givepokemon 0x100 0x19 0x44 0x0 0x0 0x0

this script means :
0x100 -> pokemon ID / index number
0x19 -> Pokemon Level
0x44 -> Item that pokemon holding
0x00 -> unused byte
Did you already give right number?
