Tell us what’s happening:

I’ve tried the suggestions on the forum. I pushed newWeapon to the inventory array but the console says not only to ‘push’ but also ‘add’ newWeapon to the end of the inventory array. I’m confused because I thought I already added newWeapon to the end of the inventory array with push.
Console:
// running tests
Your buyWeapon function should add the value of newWeapon to the inventory array.
// tests completed
// console output
[ReferenceError: Can’t find variable: currentWeaponIndex]

Your code so far

<!-- file: index.html -->


/* file: styles.css */


/* file: script.js */
// User Editable Region

function buyWeapon() {
  if (gold >= 30) {
    gold -= 30;
    currentWeapon++;
    goldText.innerText = gold;
    let newWeapon = weapons[currentWeapon].name;
    text.innerText = "You now have a " + newWeapon + ".";
    inventory.push(newWeapon); 
  }
}

do you see this error? it’s why nothing works. Reset your code so you also restore this variable. Then try again to follow carefully the instructions

3

For some reason the variable currentWeaponIndex has been changed to currentWeapon, in the declaration, and where it’s referenced (twice) in your buyWeapon() function.

4

When I change both currentWeapon variables to currentWeaponIndex I still get the same console output.

function buyWeapon() {
if (gold >= 30) {
gold -= 30;
currentWeaponIndex++;
goldText.innerText = gold;
let newWeapon = weapons[currentWeaponIndex].name;
text.innerText = "You now have a " + newWeapon + “.”;
inventory.push(newWeapon);
}
}

Make sure that part got fixed too

That worked! Thank you. I’ve never had to edit outside of the edit region under the instructions before, I guess I wasn’t thinking I’d have to do that.

In Step 8 the variable was declared as currentWeaponIndex, so it must have been changed at some point later. I don’t know the course so not sure if it’s a bug or an inadvertent edit.

the whole project has been recently changed to have that variable named currentWeaponIndex instead of currentWeapon. The old code seems to persist sometimes, I’m sure there is some cache issue somewhere
