PL/SQL and nulls

I have a PL/SQL procedure which is inserting records into a database.

The values to put into this database are taken from various variables that I have created.

I'm getting the following error message when I try to insert into the database:

"ORA-06502: PL/SQL: numeric or value error"

... because (I think) some of the variables are NULL. The corresponding columns in the table aren't "NOT NULL", though.

What am I doing wrong?

Any help'd be appreciated - thanks.
