PokeMart possession??

Hi, I seem to be having some real problems creating a new Pokemart. I originally used Pokescript for this. But when I was having too many problems trying to figure it out, I moved to XSE. I really like this new Script editor, because I was able to suck up an original Pokemart script, modify it with a new script offset for mine, and simply change the item numbers.

Yet, both script attempts end up when I stop talking to the shop keeper, my sprite somehow copied over the girl sprite in the store, and I am able to walk around with the new sprite in a little limited box space, and can't do anything....and I don't know why my character is possessing another person. It doesn't make sense at all.

I thought maybe it was the script, but why would it do the same thing with a totally different script, and editor? Then I thought it was the girl, or the old lady running the store, or maybe something in the header. But I can't find anything, and I don't know where to look anymore.

Can you please help?

Thank you,
