Hi Deb ,
As far as I can see , using radio buttons will take away from the existing system.
If Checkboxes 1 , 2 and 3 pertain to a certain feature 1 , and Checkboxes 4 , 5 and 6 pertain to another feature 2 , and feature 1 and feature 2 are mutually exclusive , then how do you implement this by using radio buttons ?
What this means is that a selection system which needed two hierarchical levels is being sought to be implemented using only 1 level.
What can be done is to use the Checkbox_Click event macro to ensure that if any of the checkboxes in one set is checked , then all the checkboxes of the other set are disabled ; to gain access to the other set , you will have to uncheck all the checkboxes of one set , so that once again both sets of checkboxes are enabled.
