Have you ever been stumped by those weird "Fast Lookup" things? Or do loops and collection variables have you puzzled? This post hopes to explain those concepts while covering some of the basics of using a loop in a flow. I'm going to cover the basics of using a loop in a flow. To save you the time, here's a link to install the config I'll be using if you'd like to follow along: Basic Flow Loop Config When you feel good about this, learn how to launch the flow from Process Builder or a Visualforce page in my next post: Launch a Flow From Process Builder or Visualforce .
