The below updates all line item descriptions from the body memo field using a client script with a 'field changed function' and is deployed on the sales order. I would like to change this to trigger on save instead. I have tried to change to 'save record function' but it doesnt work. I have also tried to change the script type to an event script with no joy.

  

function description(type,name){             if (name == 'memo'){                var description = nlapiGetFieldValue('memo');                 var count = nlapiGetLineItemCount('item');                     if (count > 0){            for (var x = 1; x <= count; x++){               nlapiSelectLineItem('item', x);               nlapiSetCurrentLineItemValue('item', 'description', memo.value, false, true);               nlapiCommitLineItem('item');             }        }              }      }
