I have a winform c# app that is used as an inventory management system and posts items on eBay auction. We're trying to add compatibility to the parts and when trying to revise the listing to add compatibility info, I'm getting the following error:
"No <Item.LookupAttributeArray.LookupAttribute> exists or <Item.LookupAttributeArray.LookupAttribute> is specified as an empty tag."
However, the API reference states this:
ConditionID (added): ConditionID is supported in the Sandbox for a few categories. Starting in May 2010, it will be functional in production for most categories. Use ConditionID instead of AttributeSetArray, LookupAttributeArray, or ItemSpecifics to specify the item's condition when GetCategoryFeatures shows ConditionEnabled=Enabled or Required for the listing's primary category.

Disregard. There was an issue w/ the version.
