QT Pro problem

[mike777]

Hi

 

I've installed QTPro and it works brilliantly, but I'd like to change the multiple_dropdown to a single_dropdown display.

 

But when I try to edit it in Admin under Product Info Attribute Display Plugin I get this error:

 

Fatal error: Call to undefined function: tep_cfg_pull_down_class_files() in /home/mysite/public_html/catalog/admin/configuration.php(125) : eval()'d code on line 1

 

Any ideas what I've done wrong?

 

Thanks,

Mike
