Hello Lilly!
I'm happy your back to try again! I applaud your tenacity.
The best hint I can give you about the table code is that the first part of the Cypher is
"Base ____"
If you look at the picture on the table, it should tell you which number base Cypher.
Another hint for numbers: Think like a roman!
Lemme know if you need help or need more hints. Enjoy and good luck!
