📝 Problem Statement

You have created your first UiPath workflow, but you’re not sure whether it is executing correctly. How can you quickly verify that a specific step has run without using complex debugging steps

Display a confirmation message with a pop up when the workflow reaches a specific step.

📥 Input

User Name = "My Automation Time"

• ❌ Using the wrong variable name.

⚖️ Message Box vs Write Line vs Log Message

Activity	Interrupts Execution?	Saved to Logs?	Best Use Case
Message Box	✅ Yes (popup)	❌ No	Learning, attended automation
Write Line	❌ No	❌ No (Output panel only)	Quick dev-time checks
Log Message	❌ No	✅ Yes	Production, Orchestrator monitoring

💡 Best Practices While using This Activities

• Use Message Box only for debugging or attended automation.
• Use Write Line for lightweight checks while building the workflow.
• Use Log Message in production — it’s searchable, filterable, and doesn’t block execution.
• Avoid vague messages like “Done” — always show what actually happened (e.g., variable values, item counts).
