Oninit® Troubleshooting Guidance

Reasons / Common Causes

-2975 fires when a tag-name defined in SCREEN is never used in ATTRIBUTES — per the official guidance, this is the mirror case of a tag defined in the screen layout but not associated with a column.

A tag-name present in SCREEN but not defined in ATTRIBUTES, per the official guidance — the direct, only cause.

Solutions / Resolution

Review the tags in each section, per the official guidance.
Revise the form so that all tags are defined, per the official guidance, either by adding the missing ATTRIBUTES entry or removing the unused tag from SCREEN.

Examples

A SCREEN tag missing from ATTRIBUTES

SCREEN
{
Order #: [ordnum]
Status: [status]
}
END

ATTRIBUTES
  ordnum = order_id;
-- -2975: "status" appears in SCREEN but has no ATTRIBUTES entry

Corrected

ATTRIBUTES
  ordnum = order_id;
  status = order_status;

Diagnostic Checks

Check every tag-name in SCREEN against ATTRIBUTES, and add or remove entries so every tag is defined.
