SPD 2013 Foundation List workflow does not always fire on Item Change

Question

I have created simple List Workflow on document library using SharePoint designer, set the workflow to run on Item Created and Item Change.

I set Reviewer dropdown, this contains 3 reviewers emails(AD users), another dropdown contains 'UnderReview','Reviewed' option. When first time WF starts it runs fine. But when Reviewer edits the doc lib and selects the second or third Reviewer WF won't fire on ItemChange.

Please suggest where I am doing wrong?

Answer 1

The workflow should be working properly, but your issue at the first if condition and second else that never reached .

where you are set strEmail to current item:reviewer , then check if the email is not empty , so it's never going to second else because the strEmail is not empty.

Try to remove if condition at strEmail is not empty , and make sure that the else condition for the second else is related to if itemreviwerstatus equal "status1"
