If you format the table deffintions like this:
create table name(
col1_name col1_type col1_qualifiers,
col2_name col2_type col2_qualifiers
);
-----OR EVEN BETTER------
create table name(
col1_name col1_type col1_qualifiers,
col2_name col2_type col2_qualifiers
);
You will get more takers for helping you.
