Thanks for the reply, I am using Ubercart 5.x-1.0-rc4

I also just retested and it still outputs the o#a# format even though the instructions on the cart links correctly describes the a#o# format.

(I am adding this option to my cart from a Gallery2 photo gallery module in a Drupal site, it works perfect...now I want to display the g2 image in my cart...any ideas appreciated)

thanks
