No, that didn't work either. Here's what I got when I implemented your suggestion:

"Parent object will not allow this property setting for frmrendx.grdtables.column1.chkseelcted.controlsource."

Parent object will not allow this property setting for "name" (Error 1767)
You have attempted to set a property value on an object whose parent is controlling the setting of that property.

For example, when you try to set the ControlSource property of a contained control in a grid column, and the Bound property for the grid column has been set to true (.T.), you will get this error message because the ControlSource property for the control is taken from the grid column’s ControlSource Property.
