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!"
