on rule 18: "The elements in your password must have atomic numbers that add up to 200." My element is "Na" and it says my roman numerals are a problem. They are "VI" and "IV". Not too sure where to go from here.
the roman numerals are all good man its the elements. the "N" in "Na" is adding 90 onto the numeral rule, for rule 18 you can use multiple two letter elements just try and find ones that don't contain roman numerals and you'll be fine
