Hi all
I'm trying to disable button "CloseAsWon" in opportunity, with XrmToolBox.
The button must be disabled until the value of field [opportunity][stepname] not equal to value "4-Chiudi"
I follow this example "ribbonworkbench.uservoice.com/.../121427-enable-disable-a-ribbon-button-dynamically-based-o" but I'm not able to find the way.
This is my screenshot
where I'm mistaken?
