Undefined variable: index

Hi.

I'm getting this errors with Content Analysis:

Notice: Undefined index: sections in contentanalysis_analysis_form() (line 264 of C:\wamp\www\drupal\sites\all\modules\contentanalysis\contentanalysis.module).

and this:

Notice: Undefined index: main in contentanalysis_analysis_form() (line 265 of C:\wamp\www\drupal\sites\all\modules\contentanalysis\contentanalysis.module).

Any ideas?

Tks.
