I&#39;ve been getting a bunch of duplicate entry errors on a site, something like this:<br><br>user warning: Duplicate entry &#39;81-0&#39; for key 1 query: INSERT INTO 
content_field_testimonial (vid, nid, delta, field_testimonial_value, 
field_testimonial_format) VALUES (81, 81, 0, 
&#39;&lt;p&gt;&lt;em&gt; ...trimmed... <a href="http://judylarkins.com/html/sites/all/modules/cck/content.module" target="_blank">/sites/all/modules/cck/content.module</a>
 on line 1213.<br><br>Some searching suggests auto-incrememnt is not set, and in fact none of the fields in the content_field_testimonial are auto-incrementing.  However, before I arbitrarily assign auto-increment to any of the fields, I thought I&#39;d ask which if any should be auto-incrementing:  vid, nid, delta, field_ccktype_value, field_ccktype_format.<br>
<br>Thanks,<br>Brian<br>
