How to Get Error Column Name

Hi all -

After researching it seems as though the solution to getting the error column name is best found here: http://dougbert.com/blog/post/adding-the-error-column-name-to-an-error-output.aspx.

I am having trouble figuring out how to populate the "Reference Table" of column IDs mentioned in the article.  

Any help (or other suggestions) is greatly appreciated!
