The syntax for FOR EACH from the help file is "FOR EACH Var IN Group" where Group is:

A Visual FoxPro array, an OLE array, a Visual FoxPro collection, or an OLE collection.

The Columns property on a grid is an array (or a collection, but I think its jsut an array) and thats why Cetin and Wilfred's solutions work.
