I’m trying to create “onclick” like this example (if(validateField(’ManagerApproval’) && validateCheckBoxSingle(’AssignedBusinessUnit’)) ) but recieving an error “A nam was started with an invalid character”. Without “&&” everything is fine.
What could be the cause of this problem?

when I create a workflow in sp designer, I use “Collect data from user” action and create a field named as “ApprovalStat” However, when the user he select Approve or Reject then hit the “Complete Task” button. however, this field never changed. Remain same again.

Thanks in advance.
Kind Regards.
