It's simpler than it sounds- maybe I can help!
1) Let's say, you have 100 gold- search for 201 in Cheat Engine. Remember, you're searching for 2 times [value you're looking for], plus 1. If you're having trouble calculating, Google has an online calculator.
2) Buy or sell something- say you buy a potion for 25 gold, leaving you with 75 gold. Search for 151 in Cheat Engine. if you're lucky, you'll be left with a single value in the Cheat Engine Window. If not, keep buying and selling until you do.
3) Double click that value- it should appear in the big white portion below in the Cheat Engine window. Double click
that and change it. Remember, RPGmaker values are *2+1, so if you want 1000 gold, change the value to 2001.
THAT said however, TLS has anti-cheat measures in place, so check

for details on what to cheat on, or how much to cheat. There are RPGMaker save editors
here, though I'm not sure how reliable they are with respect to TLS. If you like, you can use

(temporary linbk, so get it while it's hot!), though odds are it's one of the editors I mentioned before and I'm just too dumb to realize it.
In any case, have fun!
