You can write a client script on Task table onChange on field name State.

var catalogitem = g_form.getValue('u_item');

if(catalogitem=='Your catalog Item')

if(newValue==closedvalue && catalogitem=='Your Catalog Item')

{

g_form.seReadOnly('variables.Yourvariablename',true);

}

Where I attempted to create a new UI policy, it wouldn't allow me to drill down to my list of variables. When I navigate to the field name list and add, there is only one selection for "variables".
