Scripting

Hello all,

I'm trying to show / hide features depending on a property value, the serial number, depending on the value shows or hides a set of features.

I've set 2 conditions to every  feature Level =0 if serial is not the required, and level=1 if it is the required. when I try to install the msi, the dialog of custom setup appears empty.  Instaling the msi silently  the msi works fine, installing depending the value of the serial I've set at command line.

Which should be the correct UISequence? 

Thanks in advance for your help
