You need to configure the rules for your initiative. The default (for historical reasons) is to add an attribute named dexterity to a d20 roll. Youll have to remove that rule first: !group-init --del-group 1 then add a new one: !group-init --add-group --bare|initiative_total I'm not certain if this is exactly what you need, but I think that's it for the OGL sheet.
