Yes, each variant consists of two attributes with a single customid. Option 1 (Scale) has three possible values; option 2 has two possible values. That's a total of six possible variants and each variant has a customid. What is perplexing to me is the different number of customid's displayed. That is, I ordered three of the six possible variants. One had the correct customid, another had two customids displayed, and another had four ids displayed.

I'll try your fix next.
