I found a lot of mistakes and had to fix them in order to get this thing to work.

On on line you are referencing an IDENTITY against a table that does not exists. The table in question is HIST_ERROR_LOG, I had to change it to ERROR_LOG. I found some other things that needed to be fixed, i.e. missing commas, ' instead of ". Aside from all that, this error handling template works great.

Thank you very much.
