Disabeling dropdown field on form

Hi Jillian, Using your code mentioned does not work on 11 SP12 and SP14. Starting with SP11, the behavior for List, Item, and Classification type properties have changed for the new type-ahead feature. Is there some other way for us to work with these types of properties? An error of "Internal Error: event handler failed." is returned. Below is the details of the error from the dialog. Event handler failed with message: TypeError: Cannot set property 'disabled' of undefined [function onformpopulated$user$handler(e) { try { if (onformpopulated1(e) === false) return false; if (onformpopulated2(e) === false) return false; if (onformpopulated3(e) === false) return false; if (onformpopulated4(e) === false) return false; if (onformpopulated5(e) === false) return false; if (onformpopulated6(e) === false) return false; } catch (exp) { aras.AlertError(aras.getResource('', 'ui_methods_ex.event_handler_failed'), aras.getResource('', 'ui_methods_ex.event_handler_failure_msg', exp.description ? exp.description : (exp + ' [' +arguments.callee.toString()+ ']')), aras.getResource('','common.client_side_err')); return false; } }] Ben
