What did I do wrong? It won't does not work for my choices...

Edited 6 Years Ago by Nick Evan: added code-tags

Please post with code tags!

This line in displayTotal:

for (int x = 0; x < 12; x =+ 1)

Should be this:

for (int x = 0; x < 12; x += 1)

Notice the += instead of =+ (this would mean "x = +1").
