Expiration Date Validation Upon Fulfillment

Developed this code today and thought I would share it in case anyone is trying to do the same.  This script keeps the save button from firing and prompts a warning and loads the NLcalander to submit a date for expiration of product if it is specified in the item record that the product expires.  The calendar will only fire in IE currently as firefox does not support the click function.

Thanks to Hazel Hernandez at Netsuite support for the quick help with this.

function expirationVerify() {   var lines = nlapiGetLineItemCount('item');   for (var line = 1; line<=lines; line++) {     expires = nlapiGetLineItemValue('item','custcol8', line);    dateField = nlapiGetLineItemValue('item', 'custcol_expiration', line);    if ((expires == "T") && (dateField == "")) {     alert('Enter an expiration date for line item ' + line + '!');     rowNumber = line - 1;     itemRow = "itemrow";     itemRowNumber = itemRow + rowNumber;     helpercalendar = "_helper_calendar";     itemcustcol = "custcol_expiration";     calendar = itemcustcol + line + helpercalendar;     document.getElementById(calendar).click();     return false;    }   }   return true;  }
