function validateFields() { var aList = nlapiGetFieldValue('custitem19'); //[This is the internal ID of the first list] var bList = nlapiGetFieldValues('custitem20'); //[This is the internal ID of the second list] var bLength = bList.length; if(aList != bLength) { alert("Select the exact number of options you selected");return false; }return true;}
