error T0013: Could not understand the attribute '%s' for a modifier.

Cause

This error occurs when an incorrect attribute(%s) is used along with modifiers like Add, Delete, Replace, and so on in a definition.

Solution

Check for spelling mistakes and use the correct attribute.

Example

[#Menu: Gateway of Tally]

Add: Items: "My Report": Display : My Report

Since the attribute Items is not a valid attribute with Add modifier for the Menu. So the message error T0013: Could not understand the attribute 'items' for a modifier. appears.

To correct the code, changed the attribute Items to Item.

[#Menu: Gateway of Tally]

Add: Item: "My Report": Display : My Report
