>How can I shuffle a set of command buttons(15) in a container. No two buttons can occupy the same coordinates. The coordinates have to be LEFT(2,32,62,92) TOP(2,32,62,92). Something similar to the puzzle in Fox 2.6. Thanks!

Set up an array of coordinates and make that a property of the container. MyArray(15,3)
1 - .top
2 - .left
3 - assigned

Set the container to default visible = .F. In the container's init, randomly assign the values from MyArray to each button until each element has been used. Use a FOR... ENDFOR to scan through the buttons.
