 <!-- Paste the full traceback or describe the wrong behaviour. Include the
 exact error message and the line of your code that triggered it. -->
 
+During Task 1, I encountered two main issues. First, an accidental import was added:
+`from curses import raw`
+This caused potential environment errors. Second, the `clean_salary` function did not return a value in all cases.  
+If the input was not a digit, the function would exit without returning anything, which caused unexpected behavior.
+
 ## The Prompt
 
 <!-- The exact text you sent to the LLM. Include the code you pasted with
 it. -->
 
+I asked ChatGPT:
+
+"My function clean_salary sometimes doesn't return a value. Here is my code:
+
+def clean_salary(raw: str) -> int | None:
+    cleaned = raw.strip().replace(',', '')
+    if cleaned.isdigit():
+        return int(cleaned)
+
+Why is it failing and how can I fix it?"
+
 ## The Solution
 
 <!-- What did the LLM suggest? Did it work on the first try, or did you
 need a follow-up? -->
 
+The AI explained that my function was missing a return statement for cases where the input is not a valid number.
+
+It suggested adding:
+
+return None
+
+at the end of the function.
+
+After adding this line, the function worked correctly on all test cases.
+
 ## Reflection
 
 <!-- A few sentences on: did you understand WHY the original code was
 broken, or did you just accept the fix? What would you do differently next
 time? -->
+
+I understood that the problem was caused by missing return paths in my function.  
+At first, I just followed the AI suggestion, but then I realized that in Python every condition must return a value or the function will return None implicitly.
+
+Next time, I will first check all possible input cases myself before asking AI for help.
