Error message 'The Condition evaluates to false' using Form Personalisation

Hi,
In Oracle HRMS
Under Assignment screen 2 fields are there 'Grade' and 'Payroll'
w.r.t Grade field Payroll field should display
i.e. If we enter grade field '1' by default Payroll field should display value' MANAGEMENT PAYROLL'

NAVIGATION: India HRMS Manage--->People Enter and Maintain--> Click on Assignment button

I done the process using form personalisation:

*Under CONDITION TAB******
Trigger Event: WHEN-NEW-ITEM-INSTANCE
Trigger Object: ASSGT.PAYROLL_NAME

Condition-- :ASSGT.GRADE_NAME IN (1,2,3,4,5,6,7,8,9,10,11,'MT','4A')
Processing Mode: both

*Under ACTIONS TAB****
Seq--10
Type--Property
Object Type: Item
Target Object: ASSGT.PAYROLL_NAME
Property Name : VALUE
VALUE
