My Sapling account does not let me type in capital letters for elements. I ran into this problem in the Tutorial and also with my organic chemistry problem #25 in my ch. 2 homework. I tried to type in N for Nitrogen, but it only came up as n. I tried caps lock and using a different computer, but it still will only do a lowercase letter. Is there a way to fix this so that I can answer the question on my homework? Thank you!
