Q: Why am I getting this "Error - Missing required variation specifics."?
A: This means that the variations for a multi variation listing on eBay are either not entered or not entered correctly.
The eBay variations need to be entered into the eBay Variation Field in the following format:
Variation Label|Variation Value
exactly as they are on the eBay listing.
For example,
Color|Black
If the listing has 2 or more parts, let's say size & color, then you separate the pairs of variation label and value with ** like this
Variation Label 1|Variation Value 1**Variation Label 2|Variation Value 2
For example, if it were a shirt and if the variation labels were "Color" and "Size" and the values were "Blue" and "Large", it would be written as follows: Color|Blue**Size|Large
