Well, I'm not sure I can teach you any better than those tutorials. The way I learned was decompiling existing scripts and studying those. Try reading one again, in XSE press F1 to get a command help menu where you can get commands. Anywho, you don't really need to know what the first 2 lines of a script does.
#dynamic 0x740000
#org @start
Those two lines should be the same for you every time. From there just write your script.
Hmm, I'm looking at your thread and it seems to me that most of your problems are issues regarding a knowledge gap of certain features in A-MAP. Have you tried reading through the A-Map tutorial by link112? That should help you, and perhaps a look at a scripting tutorial wouldn't hurt either.
I see that you've received some help from a few other members as well. What they're told you is correct (except needing to get rid of your ROM). Just read up on those tutorials and you'll be fine to go I'd say.
