dannessicity

First off, I am sorry if this isn't a sticky, or if I put this in the wrong place. (I'm kinda new) I've been using ppre to edit pokemon diamond. It has worked wonderfully for all the areas I've tried to edit. One thing I've tried to accomplish, and have failed at, is finding the coordinates for a new script. I downloaded a untrimmed rom, and tried to use the LUA script to find these coordinates; but so far it hasn't worked for me. (Note: I downloaded a LUA specifically for pokemon diamond) The 'y' is either at '0' OR 'x/y' are both in the 1000's range. I know this cannot be right. Am I doing something wrong? Is there any other way to find these coordinates? Any help would be gratefully appreciated!
