The goal is to use expressions to pull specific data from the **\"Source Data\"** node.\n\n**How to use this test:**\n1.  For each step, read the instructions on the purple sticky note.\n2.  Modify the corresponding **\"Test - ...\"** node by writing the correct expression in the value field.\n3.  Click **\"Execute Workflow\"** to check your answers.\n4.  A green path means a correct answer, a red path means it's incorrect. Keep trying until the path turns green!\n\n\nGood luck!"
