Logical Database selection screen pushbutton

Hello All,

I need to create a pushbutton on a selection screen of a logical database. Basically this pushbutton when clicked will either display or suppress some fields on the screen. I have tried to use the SSCRFIELDS option to create a pushbutton, however that never displays for me. Logical Database DDF has an example of a pushbutton that I am looking to create, however the functionality will be different. I am not sure what I am missing, can anyone help? Thanks.
