When importing a CSV into Magento with the MAGMI importing tool, I am unable to import Custom Options (as in size: smalee/medium/large). The import manages to put in the basic products, but the Custom Options don't transfer accross.

By custom options I mean the fields

Title, Input Type, Is Required,  Sort Order

    Title,    Price,    Price Type, SKU,    Sort Order
    Title,    Price,    Price Type, SKU,    Sort Order
    Title,    Price,    Price Type, SKU,    Sort Order
    and so on ...

Found in the custom options menu...

Even using the example CSV from the MAGMI SourceForge Wiki:

sku,name,description,price,Size:drop_down:1
T-Shirt1,T-Shirt,A T-Shirt,5.00,Small|Medium|Large
T-Shirt2,T-Shirt2,Another T-Shirt,6.00,XS|S|M|L|XL 

...it fails to import the attributes.

So i'm simply using MAGMI with the supplied example data from SourceForge on a blank magento product list, and it doesn't transfer properly.

Can anyone shed any light on what might be wrong?

I am using Magento ver. 1.6.1.0 if that changes anything.

Thanks.
