Nvm, figured it out by myself, just added http://lua-users.org/wiki/SimpleRound to the function. I updated the https://test2.wikipedia.org/wiki/Module:Molar mass calculator page if you'd like to see my current code (which I have tested btw in my chembox and in my /Template:Molar mass calculator/)

Oh hey one other thing, how do I get the module to round the result to 3 decimal places?

Any one know how to overcome this problem, or are yas all stumped?

I've added some error handling to
https://test2.wikipedia.org/wiki/Module:Molar_mass_calculator for you; most likely it was trying to use a quantity of empty-string for any elements you didn't specify in your Chembox, which tonumber() converts to nil. You could
probably also have had your Chembox pass 0 as a default (e.g. {{{Ag|0}}}
instead of {{{Ag|}}}).

If it's still not working, feel free to put your test cases on test2wiki so
we can see them directly.
