Stock by Attribute v4.0 addon for v1.3.5-1.3.9

[kuroi]

I just installed this mod and have the following problem.
When "Add Quantity for Product Variant" I can select the varant from the drop down menus of attributes OK, but then when the variant is listed as
Stock ID Variant Quantity in Stock etc
all the variant are just listed as ":".
Presumably this column is supposed to show the value of the attribute.

Now I have no way of telling which variant is which,

Any ideas?

There is a fix for this in a maintenance release 4.2 of this mod awaiting approval from the Zen Cart team. I'm afraid that you will need to delete out the corrupted variants and re-enter them as the details that don't appear on your screen won't be in your database either. To upgrade simply replace all the files in the old mod with those in this version. It's a one-to-one match.
