FIXED!!!

I had multiple problems with my grid column that contained the checkbox.

First, I had the ControlSource for that last column set as (None). I had set the ControlSource in the Checkbox itself in error. I should have set the ControlSource for the column, not the control.

Second, I had the ControlSource as m.fieldname which caused the Checkbox not to save the value after checking the box. Since the grid column has no property for Click Event I could not do GATHER FIELD fieldname MEMVAR MEMO in the Click Event as I normally do in a checkbox. I removed the - m. - from the ControlSource and just had the fieldname and then the checkboxes saved.

Thanks again for pitching in. You gave me some great ideas. I don't think I will ever forget this solution. I found the answer on Pgs. 69-71 of the MS Visual FoxPro 6.0 Programmer's Guide by studying the coding example for a control in a grid. There's more on Pgs. 299-306 which is where I was looking yesterday, but I should have been looking at the other pages too.

Take care. Time to move on.
