db problem? CubeCart_config table

[Guest]

In my CubeCart_config table in my database, I am getting question marks instead of the little pencil and X icons next to some items (config, Print_Order_Form and PayPal). When I hover over the '?' I get a message that says, "You should define a primary key for this table".

Anyone know how to do this and what the primary key would be?

Thanks,

Jenny
