[OpenSIPS-Users] dlg_val before create_dialog

[Bogdan-Andrei Iancu]

Hi,

Yes, the dlg_val assignment fails if there is no current dialog. Maybe 
the dialog is created (internally) by some other script function you are 
using. Try prinitng the $DLG_status before the assignment, just to see 
if there is a dialog or not
