[Script] I need help creating a new script

Hey I'm new to pokecommunity and to rom hacking I started the video series from Anthroyd here on pokecommunity and I tried to replicate what he did in his basic scripting video but when I want to change the events number so I can add my new script this windows pop up



I managed to insert the event but it appears somewhere else and not in the place I set it and with a different mini



any help you can give me guys? Thanks.

I do not understand scripts at all, however I worked a lot with hex, the fact is that these five lines starting with line $ is the address in ROM, and there are downloadable data, try to paste into the script, this address, usually it is mentioned in the script in the first If it's off topic, sorry
