Hi,
We have started using the product import feature, but have run into something odd, when we try to import larger datasets, we run into an error like "Invalid import file format. Min (1) must be less than or equal to max (-1) in a Range object." but if we break that same dataset up into smaller ones they import fine (10 records no problem, 20 records failed consistently until broken up).

Also does the import do updating or is it only creating new records? And if it updates, what does it key off?

Thanks,
Rob
