Unfortunately at the moment the nearest VFP6 with SP3 is 2 kilometers away. What is the problem that you are experiencing? Come on, spill it. :-)

>Try this, create a form. Put 2 standard CB s on it. Add a command button with a Click like:

thisform.combo1.readonly=!thisform.combo1.readonly
>thisform.combo2.readonly=!thisform.combo2.readonly
