I created a custom button for custom object to place in the related list. The custom object has two look-ups, one for case and one for account. This button, when clicked, should open in a new window to save a record of the custom object, with the default values for each look-up to populate automatically depending on the record where the button was clicked. It works for every record so far, except one case. It then throws the error: A problem with the Onclick Javascript for this button or link was encountered: Unexpected identifier.
I couldn't find any differences between records where it works and doesn't.
Code:
window.open('a2U/e?CF00N600000037HI4={!Account.Name}&CF00N600000037HI4_lkid={!Account.Id}&retURL=%2F{!Account.Id}&CF00N600000037HI5={!Case.CaseNumber}&CF00N600000037HI5_lkid={!Case.Id}&retURL=%2F{!Case.Id}','','scrollbars=no,menubar=no,height=600,width=800,resizable=yes,toolbar=yes,location=yes,status=yes');
