Can't Add Multiple Keys?

Hi! A while back i bought a fairly large bundle off of GMG, and i've been slowly giving away the keys over the last few days since i find it more "rewarding" to myself than just trading them off. Only problem: There are a few games that i have multiple keys for, and while the system recognizes that i have multiple keys added, it won't add the giveaway, giving off an error that "keys can only consist of Numbers, Letters and Dashes." Only thing is, i followed the instructions perfectly, and i know that my account has decent enough feedback that i can at least post two keys. Anybody else had this problem and/or know how to fix it? (Edit: I'm an idiot. x3 Fixed it.)
