Fatal Error when I try to run cron

Just today I got this error when trying to run cron:

Fatal error: Call to undefined function uc_attribute_get_name() in /home1/oregonfb/public_html/sites/all/modules/ubercart/uc_attribute/uc_attribute.module on line 325

I've been trying to set up Ubercart to handle events but really haven't changed much of anything so I have no idea where or how to fix this. Could someone please help me? What the heck is this error saying?
