SQL Script File is failing but not showing an error - sql

Question

I have ran this Script File on Oracle Application Express and it does not create my tables and does not state that I have errors. If you can't help that is okay, but I have been at this for hours and cannot figure out why it is not working
Here is my Script File:
CREATE TABLE GUEST_T

There are a lot of issues in your script (and they do show up when the scripts runs). The most proeminent ones are:
the same constraint name is used in several tables; a constraint name must be unique in a schema, you can prefix them with the table name to avoid clashes
various typos : missing underscore, missing spaces, missing commas
funky quotes ‘’ instead of regular quotes
wrong table creation sequence: a parent table must be created before its dependant tables
side note: you want to use VARCHAR2, that Oracle recommends to replace VARCHAR
Here is a new version of your script that works fine in this DB fiddle. All the changes are commented:
