Yes, I've read the User and Rule Guide, but the samples don't work.
My expresion is:
<<IF DocVentaFRA1.Bloqueo='Yes' Then SHOW SystemSettings.Icono_Candado>>
I want display a image (SystemSettings.Icono_Candado) when a Yes/No field (DocVentaFRA1) is True.
This expression is in a html cell in a form of the object DocVentaFRA1. And If I remove the conditional part works fine
