Hello,

I'm only new at this so please bear with me! I am creating an ontology
for a color game and i am using the pizza tutorial as a basis for it.
I did everything and when I went to save the file I get a message saying
save project errors with these error messages:

I have no idea what could be wrong?? I have a class called html code and i have
sublasses that have actual html codes-would it be anything to do with the fact
that I have numbers as names for the classes? This is for a final year project
and it won't let me save my work so i've had to re-do it five times already!!
Any help would be greatly appreciated!
