Ethan - you are simply missing two dollar signs as pointed out.  Once 
you correct them, if there are any more errors you should then be seeing 
the message from mysqli_error.

And as for the advice to dump single quotes, I'd ignore it.  The use of 
double and single quotes is a very handy feature and makes for very 
readable code.  Escaping double quotes is such a royal pia and makes for 
more trouble deciphering code later on.  The sample you provided for us 
is some of the best and most understandable code you've ever showed us.
