Hi @gideonihonre345

  1. You need to use compound assignment using augmented addition, otherwise the previous text will get over written.
  2. Add a single space after the colon.

Happy coding

text.innerText = "You now have a " + newWeapon + ".";
inventory.push(newWeapon);
text.innerText += " In your inventory you have: " ;

The order of your last three lines needed to be changed also. You will not be able to later display the new weapon until you push it into the inventory array. Displaying the full inventory is the next step (Step - 92).
