# Warnings

#### **Missing Reference**

This error appears when a segment or CBP is missing a default action. These warnings are stated as such: "Segment '(X)': no default action", "Conditional Branch Point: no default action".

In order to resolve this validation warning, the default actions need to be assigned a consecutive segment, or if the default action of a segment is assigned to button, this button should be designated as the default action.

#### **Missing Value**

These warnings occur when the values missing are not essential to the running of the script. They can be caused by a segment not having an identifier or the document version being left empty (see Segment Identifiers and Document Version). The warnings seen are as; "Segment: no identifier", "Document Version" and can be resolved through inserting the respective 'values'.
