I'm struggling with this one. Of course I've seen the guide from http://office.microsoft.com/en-gb/sharepoint-designer-help/watch-this-run-a-workflow-when-a-specific-field-changes-HA010256419.aspx which has been referenced by many. This example is based on SP2007, I'm using SP2010 (SP2010 Designer) and just cant get this to work in the same way...
What's happening?;
If "before" field is blank, it gets updated to match "current" - But I get an email generated stating the field has changed.
If "before" field matches "current", no further action and workflow completes - No email
If "current" field is changed, I get an email - which is what I'm looking for it to do.
I just can't get this to stop mailing me when there's a blank field - quite frustrating, tried re-working/re-formatting the workflow many times now...
I think I just need to understand how to "nest" the "steps" (or "If" statements) in a way that I can control the workflow stopping after updating the blank "before" field.
Any ideas?
