Variable - Not working

what isn't working on what slide?

In the first seen I see you set a lot of variables but don't have any triggers to do anything on the variable values.

Second scene you only have data entry

Again, in the third scene you set values, but don't do anything with them, except on last slide where you do something with a variable you haven't set.

If it is the Christmas carol then you can delete all the set triggers don't need them.

You have no triggers to change state of the characters, show the setting but the music should work
