Pulling in a div value for sMessage

kfox

I'm trying to pull in the value of a div to use in the sMessage of the print function. This code works but displays a null.

"sMessage": "" + document.getElementById('classification') + "",

The div with the id of classification does exist on the web page outside of the table and has a value in it.

If I change it to document.getElementById('classification').value, I get an error when I refresh the web page that says:

Warning: TableTools must be initialised with the keyword 'new'

Any suggestions? Thank you.
