Uncaught TypeError: Cannot read property 'parentNode' of null

This plugin looks promising, I am however getting a js error.

Javascript error : Uncaught TypeError: Cannot read property 'parentNode' of null

Not sure why, but the getElementById("") is empty:

<script type="text/JavaScript">nscrmhp = document.getElementById(""); nscrmhpp = nscrmhp.parentNode; nscrmhppp = nscrmhpp.parentNode; nscrmhppp.parentNode.removeChild(nscrmhppp);</script>

Area you getting any other PHP errors?

Based on a quick look at the code, the missing bit is derived from the label_list and the honeypot selected as label. Are you using the new method for WordPress comment form?

I can't seem to find any info about old vs. new method. I am using twentytwelve.

Looks like the array of comment fields started in the twentyten theme.

I'll give it a try with twentytwelve and see if I can't figure out what is going on.
