I would like to create a condition in Starting Rules where a workflow will only trigger if Field A does not equal Field B.  Values for both fields are available in the same template.

I know I can test for this condition in workflow and end the workflow if Field A equals Field B but I would rather the workflow not trigger in the first place.

Start Rule Example:

If all of these conditions are true

Field A does not equal %(Field B)

Starting Rules does not recognize %(Field B) as a token and, I think, is seeing it as a literal string.  Anyone know a way around this in Starting Rules?
