Here it is...I have a form where I add/edit clients.
I have a Date of Birth field which I fill in.
When I fill in the form completely I wish to lock ONLY that DOB field.
Move to a blank client record and have the DOB field unlocked and enabled.
Again I fill in the form, when I move out of that record to the next new one I wish to lock and disable that DOB field, but yet unlock and enable it for the next new client...etc...
I wish to lock a DOB field when it is filled so nobody can screw with it.
Yet with a new blank client record I need it to be accessable to fill in...
