Hi Guys,

Been struggling with this and I thought would be simple, i want to display contents of my scenario variables into a activity form presented to agent on call connect, if i have a Set Variable $(sampledata), can i display this fields contents to agent activity form ?

If i use the web screenpop i can see the information presented, but want i would want is the field contents within the activity form, i have tried the following within the activity form without success, any pointers?

$(Sampledata)
$(item.Sampledata)
$(screenpopData.Sampledata)
$(item.data.Sampledata)
$(app.custom.Sampledata)

Thanks,
Meli
