Sorry about being awol, guys! Been under the weather.

First of all, the absolute best way to create the correct fields and rows after installing this is to do it via excel. lat9 is right about the way he did his cart. However, some folks may find that to be cumbersome and may not even work for others. You need to create a row for every product you have not just the ones you think you need this on.

First, export the product_extra_fields table via phpmyadmin. Choose excel csv as the type of export and you may need to experiment to see which opens correctly in your version of excel but the csv works for me. Be sure not to leave NULL in the blank for filler for empty space.

Open that file in excel. Fill in the product id numbers for every product (type 1,2,3,4,5 - select and draw the column down to easily create your product id numbers). Save the file as csv and import in phymyadmin. Put a comma in Fields terminated by where it defaults to semicolon. Be sure to check the box to replace the table data.

I am aware that copying and deleting the product does not work correctly and will be fixing once I get a chance to do that.
