Need help to create a custom event

Thank you Madsiur, its working. :-)
But I need more help, 'm only able to make 1 character in my party.
This is working
The adress is CC9AE0
2) 40 00 01 (Assign property 01 to character 00)
3) 3D 00 (create object 00)
4) 37 00 00 (give character 00 graphic set 00)
5) 43 00 01 (assign palette 01 to character 00)
6) 45 (refresh object)
7)3f 01 00 to have character 00 in party 01
8)3f 01 02 to have character 02 in party 01(I dont see this character)
9)3f 0e 00 3f 0f 00 (biggs and wedge not in my party
I tried to add the character 02 but the fight dont start

I've done the same thing twice (point 1 to 6) and put 4d 01 3f to start a battle but... the screen goes black.



1- What is wrong with what I've done?
2-Where do I input the 4d invoke battle?
3-Do I need to create an object to have them in my party at the beginning
