Hi everyone.
I'm trying to use the prepopulate module to pre-select a taxonomy category when creating a new 'audio' type, supplied by audio.module. I have a vocabulary item called "Class" and terms under Class that include 2007, 2008, 2009, etc. The select box for Class is displayed on the page for new audio content, but when I try to pass a value via the URL I never get anything selected. The name of the form element is "edit[taxonomy][43][]" and I have tried using the following URLs with no success:

/drupal/node/add/audio?edit[taxonomy][43][]=2
/drupal/node/add/audio?edit[taxonomy][43]=2
/drupal/node/add/audio?edit[taxonomy][43][]=2009
/drupal/node/add/audio?edit[taxonomy][43]=2009

For an autocomplete field, I get the correct results. For example, the following url:

/drupal/node/add/audio?edit[taxonomy][tags][45]=value

results in an autocomplete box with "value" filled in.

I'm using the cvs version of the prepopulate module and version 1.51.2.33 of the audio.module with Drupal 4.7.4.

Thanks for any help you can provide.
