What's recordsource of the grid?

>A very stupid question. I'm working with vfp9 sp1. With vfp6 I used to put a grid on a form, put how many columns I wanted, and so on. When I run the form thew grid was always as it should be (of course), as I designed it. But the same thing doesn't happens with vfp9 sp1, I put a grid, dimension number of columns (graphically) headers, etc, etc, and when I run the form NOTHING appears, just a grid with one column only. This has got to be the new feature of vfp9 that treat columns as an object too, but I don't see how to fix this.
