Hi Germaine84,
If you're using SharePoint or a Web service you can use submit to save the form. Just add a button (label it "Save") and add an action to Submit the form. Piece of cake. Requires that the form be valid. If you have scenarios where you want to allow saves even if the data is not complete, you can use qRules ClearErrors to temporarily force validation and submit. After you add that action, you can add another action to open the Event form followed by an action to close the current form. Easy as pie.
