The main problem is your for loop. What you’ve got above is not how you do it unfortunately.
For loops in javascript take the following format:
for (var i = 0; i < maxNumber; i++) {
Notice the three sections separated by semi colons ( ; ).
Section one declares the variable i as 0.
Section two declares the boolean statement (true of false) which must be true for the loop to run. Meaning, i must be less than a certain maxNumber for it to run. You can use array.length, which contains the number of items in a certain array (like word).
The rest is also wrong, but I’ll let you try and fix that bit first, now that the for loop should work.

Thanks guys, but now I get the error letter is already defined on line 8:
// You must to find the treasure.
// This function should return the index of a letter:
function letterIndex(word, letter) {
// Step through each letter as an index of the word.
for (var i = 0; i < maxNumber; i++) {
// Store a character from the word with the current index.
var letter = letterIndex[i];
// If it is the required letter:
if (word [i++] == letter){
// Then return the current index (number).
return index
}
// If nothing, return a default value
else{
return -1
}
}
}
var ogreLetter = "z";
var shaman = hero.findByType("thoktar")[0];
// Find the index and use it for finding the treasure.
var chestIndex = letterIndex(shaman.id, ogreLetter);
hero.moveXY(16 + chestIndex * 8, 36);
