    Hi Agha,

    You can try to put the keyword 'public' in front of 'final class SalesTableAghaForm_Extension'.

    Hi Agha,

    Please try it:

    [ExtensionOf(formStr(SalesTable))]
final class SalesTable_Form_Extension
{
    public void init()
    {
        next init();

        //customize code goes here

    }

}

    Hi Agha,

    Adding method definitions is done in the same way as the base class, and this is the rule that all Chain Of Command classes must follow. In your code, the init() method is written as Init(), which causes the system not to find the method, so it reports an error.

    Hi Agha,

    Can you try to add additional coding? You now only have the 'next' command, but no actual coding.

    Hi,

    I think because you have Capital letter on Init, it should be init in lower case. Please check.

    Thanks
