                         Issue: The app is not responding to clicks on the "Convert" button.

                        o  Solution: Check that the button's ID matches btnConvert in both the design and code.

                         Issue: The output always shows "Invalid Input."
                        o  Solution: Ensure the dropdown menu IDs (convertFrom and convertTo) are correct
                            and initialized in the code.

                         Issue: Conversion results are incorrect.

                        o  Solution: Verify the mathematical formulas in the code for accuracy.
                         Issue: The app crashes or shows errors.

                        o  Solution: Use console.log() to debug the variables and confirm correct data flow.

                         Issue: Nothing is displayed in the result label.

                        o  Solution: Check the ID of the result label (outputResult) and ensure it matches the code.
