Found a few minor errors related to Dance Studio.
1. Dance Contest Registration: Line 22571 col 62, should be "Dance Studio" instead of just "Dance".
2. Emily Dance Studio Chat: Missing "<span id=choice>" at line 22623 col 1, missing "#choice" at same line col 78 (col 101 after addition, right after "replace")
3. Emily Dance Studio Chat: Missing " $return" at line 22637 col 223 (after ""abilities."", keep the blank)
4. Emily Dance Studio Chat Choice (Chat/Just say hi): Line 22637, delete col 366 to col 506 ("<&silently…/silently>>") to get rid of the error text, disregard if you have other plans for it =)
Hope this helps, keep up the good work!
EDIT:
Found another one (housekeeping course), line 3081 col 1083, deleting the if/if enclosing "PM", and adding value (870) at line 4041 col 1172 fixed it for me.
And line 3091 col 107, missing "<=" before the value (187).
(Is it just me or does the whole winter semester needs a bit more polishing...? )
