How to hide variables in multi row variables set

[Xhare]

I'm trying to hide one variables (action) in my multirow variables but its not working with client script.

var requestType= g_form.getValue('request_type');

   if(requestType =='add_location'){

    g_form.setVisible('action', false);

   }

A multi-row variable set works like a pop-up window and does not have the parent page/record variable details. This is one of the limitations of a multi-row variable set. If the variable on which the script is running should be part of the variable set to make it work.
