In Excel, function syntax is the specific structure or format that is followed when using a function to perform calculations or tasks.

For example, as a public health program manager, I can use the IF function to evaluate the effectiveness of a health promotion campaign based on the responses from the survey.

An error code in Excel refers to a specific value that appears in a cell when a formula or function encounters a mistake or issue. Many types of error codes can occur during calculations or data processing such as #NULL!, #N$/$A$,$ and #REF!. #NULL! occurs when the cell reference is not specified correctly due to an intersection operator $($space$)$ in the formula for example, $(=$A$1$ B$1).$ #N$/$A means "Not Available" and that the value is not found, we may get this error when using functions like "VLOOKUP" or "HLOOKUP" when the lookup value is not present in the search range, #REF! means reference error that occurs when a formula in a cell is not valid because it has been deleted or moved, or when performing
