I am trying to set up a workflow to keep me updated on the progress of one of my surveys. 

I was trying to set it up that it would send me an email after X number of responses (let’s say 5). The workflow seems to be able to send the email no problem, but I have not been able to figure out how to condition it upon the number of responses received.

For example, I want to set it up so that I would receive an email notification after Response #5, Response # 10, Response #15, and so on.

Does anyone have an idea if such a conditioning is possible and how to go about it?
