Examples of system debugging and error handling.

Category of the error	Example
	Description	Cause	Resolution	Stage

Unexpected function	When the user would close the form and then select “No” in response to the form's “Do you wish to close the application?” message, the form would move out of the window frame.	The form was attempting to save a picture when the user selected “No” to the close form confirmation message.	Disabled the image saving feature of the “No” response	Testing
Incorrect Communication	When the user responded to previously missing fields, error messages signifying missing fields would remain.	Spelling error in the code	Checked all error provider objects for correct variable assignments and ensured no interaction with other variables	Testing
eFI-CGA score miscalculations	The eFI-CGA score would not update after inputs were changed following original calculation.	Logic error in the code interpreting the formula	Checked variable mapping and ensured correct calculated value assignment	Testing
Syntax errors	“Creatinine” was spelled as “Creatine,” improper capitalization, etc.	Misspelling in the code of the GUI fields	Fixed the spelling error	Testing
Incorrect data storage	Data was saved under incorrect columns in spreadsheets	Wrong column ordering, or missing or added columns	Fixed the column ordering and added/removed columns	Testing
