Eraser not working

I’ve been trying to get this working to finish this thing but it wont work. I set everything to MASK, or transparent and it still doesnt work!

You are using a background layer (indicated by the underscored layer name), and they can’t have transparency. Right click the layer and pick “Layer from Background”. This happens when you pick “White” or “Black” background when making a file.


Thank you so much! I was losing my mind trying to fix this
