Yeees! finally lol and all because I interpreted a part of that tutorial wrong!

When it says to 'open your copy' of teleportmap.dbr for Step 4 I took this to mean I had to make a custom copy (or in other words a second teleportmap.dbr) in addition to the first one. So I did that and made my changes to my new renamed teleportmap.dbr - wrong! That's why nothing was showing up. You only import the teleportmap.dbr into your records, then open THAT one and make your new changes. ;D
Relief I tell you lol
Thank you WNG for your help
