SQL & PL/SQL

All,
We are using Oracle 10g. I have already created an object TYPE and would like to reference it and create a table. When I run the script that creates a table, I am getting ORA-00904: invalid identifier. It might be that I am prefixing the type name with the schema owner name and column name or in this case TYPE name can not contain special characters such as a dot. I am getting the same error message, if I remove the schema owner name.

Thank you for your help,

Seyed
